Aqua Hoshino/Relationships

Ai Hoshino
Being Aqua's biological mother, they had a very close mother-son bond during Aqua's childhood. In his previous life, Ai was his favorite idol and he was an obsessed fan. Coincidentally, he was the doctor in charge of delivering her twins, thus, she really trusted and actively seeks his advices. When Gorou died, he was reincarnated as her son. Despite their years living together as mother and son, he never got to truly realize Ai as a person, as she intentionally hid her true self. Regardless, the way she lived and died made him into the person he is today.

The final words she imparted to him stuck with him into his teenage years. She was always lying to appease and be presentable to her fans, however, those were all just a facade. The truth she could confidently impart to the young Ruby and Aqua was that she truly loves them. With that, Ai passed away with a smile in front of a distraught Aqua. For years afterwards, Aqua would suffer from PTSD whenever he recalls that night. He was never able to get over her death until Akane Kurokawa appeared and brought him through the ordeal of confronting his past. His main goal throughout the series was to avenge Ai by bringing her murderers to justice. After being told that the main culprit was said to be already dead, Aqua became softer as he imagines himself finally living a normal life and being happy.

Ruby Hoshino
She is Aqua's younger twin sister and one of his patients before they died and was reincarnated. He is considered to be overprotective of her and doesn't want her to become an idol, as he fears the possibility of her following their mother's grim fate. Whenever Ruby tries to follow that path, Aqua would go behind her back and sabotage her much to her unawareness.

Both of them knows that they are reincarnations but is unaware of their previous selfs identity. In their past lives, 'Ruby' was in love with 'Aqua' as he was the doctor who treated her kindly when she was dying slowly. After reincarnation, Ruby attempted to find the doctor's whereabouts but was told that he went missing a long time. Even after all these time, she still has feelings for the doctor.

Due to his overprotective nature, he gets labeled a "sis-con" by his sister and friends. Despite not displaying affection in public or when they're alone, they still truly care about each other. Even if he doesn't want to do something, he is willing to go through pain to see out his goals. Whether it be through acting jobs or participating in a reality-dating show and putting up a face. He wants to do it for his and his sister's sake.

Ruby is constantly worried about Aqua especially when he started dating. She made it known that she would despise him if he ever makes Akane sad. Furthermore, she is quick at jumping to conclusions as she once thought that the couple 'did it' all night when Aqua only returned in the morning.

Akane Kurokawa
Akane and Aqua met and became acquainted at the reality show, LoveNow. She became the target of bullying and harassment by social media, after injuring Yuki, another beloved actor in the reality show. Aqua stayed up for numerous nights to ensure that the video he published would go on to redeem Akane's reputation. He ran to save her after she attempted suicide following that very incident, saving her from jumping off a bridge during a stormy night. He then went on to reassure and silently embrace her after she had to go through such a horrible ordeal.

Deep down, he was livid that the adults and public have used and chastised Akane to this extent for their selfish goals, thus, he worked hard to ensure she rise up from this difficulty. To the public eye, Akane is his girlfriend whom has went on plenty of dates to keep up appearances. However, for a number of chapters, it should be noted that their relationship was strictly for work in his eyes. He has referred to her by her first name since before they started dating.

In chapter 31, Akane asks Aqua if their relationship was authentic or just for business. Aqua replies that they have to continue acting as a couple and that it’s not like it’s just for work. Aqua sensed her nervousness while she sensed his apprehension. She tells him not to hold back and that she knows he doesn’t see her as a woman currently. Aqua admits that she’s right but also states that he has a keen interest in her as an actress. Akane accepts his words as something she needed to hear most from him. They decide to remain a couple with Yuki and Nobu being their examples of a real relationship.

During their practice for Tokyo Blade, Akane declares that she'll be the one this time to support him. He was pleasantly surprised that she gained so much confidence in such a short period of time and promises to talk to her if anything comes up. Their respective roles were that of a betrothed couple and so, they were intrinsically linked in many scenes. When Akane comments that his relationship with Kana was rather close, he rejects that notion and found solace that the fewer scenes Kana and him had together, the lesser Kana could complain to him. Akane always keeps a close eye on Aqua and despite having a clique constantly around her, she'd always find time to escape and talk to him since he was isolated. In one instance, Aqua forebode that they may lose since Kana was adapting to the level of Lalalie's headliners. He remarks that he has no intention of winning in the first place since he has no talent, causing her to pout in response.

When the scriptwriters and Mangaka clashed on how to proceed, in the interim, Akane happily invites him on a date to experience immersive theatre for the first time after he voiced his cluelessness. Akane was elated and giggled constantly after Aqua admitted that he enjoyed himself as they continued discussing about the experience. After a new script was written, Aqua had a hard time emotionally resonating with his character. Akane softly tells him to slowly get used to it when Kana tells her to stop 'babying' him. Kana insensitively asked what he'll do if his mother died which caused him to collapse from PTSD. Akane was worried and took care of him in the meantime, which lead her to realised that Ai was his mother. As Aqua awoke, Akane was seen weeping at his bedside, which confused him. Akane hugs him and promises to always be by his side no matter what happens, and that she'll share his pain if something is hurting him. After which, she spends many hours helping Aqua find his 'trigger' through research and studying.

The next day, she cooked for him which he internally remarks that it was delicious as he blushed slightly. Aqua then allows Akane to watch his old plays, surprising Taishi Gotanda at his change of heart. Upon watching Aqua as a child, Akane was ecstatic at his cuteness but underneath it all, she knew that he was play acting. Akane decides to talk to him at night and asks why he was in theatre. Aqua attempts to dodge her questions but eventually relents under her insistence. He tells her the truth and despite initially trying to scare and intimidate her of his goal to 'kill someone', he was heartened as well as astonished at how supportive she was of him. Moreover, he was pleasantly surprised to see her support and promising to shoulder his guilt after explaining that is how committed she was to their relationship. He then accepts his role as her boyfriend by protecting her and ensuring she achieves her goal of beating Kana and Himekawa, causing her to smile.

During one of their practice, Aqua restrained Akane while Melt Narushima held back Kana after they had a heated argument. Aqua worked to calm her down and concurs with Akane's take on Kana's personality. From then on, they took their roles seriously as they worked hard together as partners, swearing to never lose. During the final acts of the performance, Akane dutifully fulfilled her role, which leads to Aqua's first successful display of heartfelt despair at her character's 'death'. His expression stunned the audience, actors and even Akane herself whom could only stare and blush silently at his face.

After returning home from a party afterwards, Akane texted him to be safe and tells him to be careful since he left early. Akane apparently also left early because of his departure which leads to others misinterpreting that they did something naughty together. As of Chapter 68, after he realised his father was dead, he recalls Taiki Himekawa words to 'figure it out soon' and to not toy around with Akane and Kana. As he reflects how he was 'finally free', and can 'live normally', memories of both of them smiling came to his mind as he can 'be happy normally'. The chapter ends with Aqua genuinely smiling for the first time with his signature star eye missing, signalling that he’s ready to progress past his obsession with Ai.

In chapter 71, Aqua turns down Kana's invitation to go out as he candidly says he has a date with Akane. It's been half a year since they started dating. During his date, he contemplates about his future with Akane. Now that his goal was complete, Akane was no longer bounded to him. Internally, he was against holding a young girl with a bright future like her due to his own selfish ego. When she mentions that she'd never gone a trip with friends before, he immediately invited her to join him and his sister's trip. He also grimly mentions that they should have a serious talk soon. Akane instantly knew that he intends to break up with her which shakes the stoic Aqua.

She suggests they talk about it now and not wait until the trip. Aqua sombrely listens to Akane as she reveals her inner thoughts about their relationship. She mentions how being with him was fun and that they didn’t as much as hold hands or kiss since the show. She adds that an unnatural relationship inevitably needs a serious talk. Looking downcast, Aqua softly remarks that he shouldn’t tie her down any longer and that as a by-product of the show, their relationship weren’t genuine. Akane asks if she'd helped him in any way and if she's no longer needed by him. She knew all along that Aqua had a secret agenda by using her but there was something she knows that is more important.

Above all, she knows he's kind and that he saved her life on the bridge without any ulterior motives. Akane embraced his back with a poignant resemblance to how he saved her back in chapter 25. Even though their relationship started off on shaky grounds, her feelings for him are genuine and remain strong after all this time. Aqua accepted her embrace as she bashfully reveal that she didn’t mind him kissing her, and doesn’t mind if they have sex.

Kana Arima
Years ago when they were just kids, Aqua met Kana at one of Taishi's movie sets. Believing herself to be the best child actress, her hubris was in full force. She was soon humbled after being outperformed by Aqua's acting skills. In chapter 52, when conversing with Akane about Kana's personality, he admitted that he'd wanted to strangle her back then and remarked that she’s always been rude. In high school, they met again in Aqua's first year and cultivated a form of friendship with her. Despite Kana addressing him by his first name, he still refers to her by her family name.

After many years, she meets him at high school and they rekindled their old friendship. He later convinced her to join his sister to start an idol group after seeing her sister in desperate need of help. It's also hinted that Kana harboured romantic feelings towards Aqua after they reunited. Kana deeply cares for Aqua in her own way, as they mutually provided support to one another in their respective businesses as well as also in private.

In the early chapters, Ruby once remarked that Kana seems to be the one of the few people who could bring Aqua back to his "old-self" after he has changed to be more aggrieved and gloomy after Ai Hoshino's death. Aqua often goes out of his way to encourage Kana Arima or more specifically the group as a whole, such as when he waved all of their glowstick's colors at the new B-Komachi's first performance. He noticed that Kana is uneasy of her performance due to the responsibilities she carries as the centre of the group.

In chapter 30, Kana cried in her room after seeing Aqua kiss Akane live on the show and calls him a jerk. In the chapters afterwards, she resolves herself to move on from him and actively ignores him whenever possible. It was to the point that she fell in love with Pieyon, after the person reminds her of Aqua. She was especially impressed by his fitness level but during one of their training when the actual Pieyon was unavailable, Aqua decides to don his disguise as his substitute. They then had a heart to heart talk as Kana felt ready to move on from Aqua. Kana decides to see what was underneath Pieyon masks and surreptitiously found Aqua after he took it off momentarily. This shocks Kana who resolves herself to make Aqua like her. From the on, Kana once again openly talks to Aqua.

When they were co-workers for the stage-play Tokyo Blade, Kana never fails to remind Akane and Aqua at every opportunity that their relationship is only for show and they shouldn’t take it seriously. Deep down, she was rather insecure though to them, she was being her usual self of being rude. She once told off Akane for babying Aqua and instead, she asks him what he'll feel if his mother had died and to recall happy memories if he wants to emotionally act. This causes Aqua to collapse whom the director immediately tells the frazzled Akane to care for him as his girlfriend. Kana then looks on jealously as she opined 'how convenient'.

The day after the party ended for Tokyo Blade, Kana immediately calls and shouts whether he and Akane did something since both of them disappeared from the party earlier than the rest. Aqua answers that he was with other people which relieves her. She ends the calls by yelling that he shouldn’t do things that confuses her and repeating he's an idiot.

Kana admits that she likes the demeanour of the new Aqua as he became warmer and more receptive to others. Kana was delighted that he intends to join them with their group's trip. Seeing how unprepared attire wise he was, Kana heavily hints to him how she's free and could even help him choose something fashionable. Aqua immediately rejects her as he frankly says he is going out on a date with Akane. The frantic Kana tells him that she’s free tomorrow and the day after. Seeing her eagerness, Aqua relents and tells her tomorrow as he quickly leaves.

Taishi Gotanda
Aqua's boss as well as mentor. Aqua first met Taishi at the age of 4 when Ai brought him to the studio. Taishi talked to him and noticed his strangely mature way of speaking, so he offered Aqua to act in his movies but was turned down. Later, Aqua took his offer in exchange for him giving Ai a job. After Ai died, Aqua asked Taishi to raise him and work as his assistant. He currently works as Taishi's assistant behind the scenes.

After Aqua promised Akane that he'll help her win against their rivals, they went to seek counsel from Taishi. Aqua told Akane to call Taishi instead of Ruby after he had collapsed from a set. Taishi was astonished that Akane was Aqua's girlfriend and had perviously thought Kana had that role. Taishi then remark that Aqua should had trained from the start if he had to go through the same thing again. That said, he happily agreed to drill everything back into him from scratch so they could win.

He was surprised when Aqua agreed to show Akane his past acts, and wonders what caused the change of his once vehement behaviour concerning his vulnerable past. Since she was his girlfriend, Taishi also revealed what he knew about Aqua's past to her and was curious as to how she could understand Aqua when they were examining his past videos. The next day, he was surprised at how well Akane could cook and concurs with his mother that 'This one's a keeper' when referring to Aqua.
