Aqua Hoshino/Relationships

Family

 * Ai Hoshino: Aqua's mother. In his previous life, Ai was his favorite idol and he was an obsessed fan. 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, her life and death alone made him into the person he is today.
 * Ruby Hoshino: She is Aqua's younger twin sister and one of his patients before they reincarnated. He wants to protect her and doesn't want her to become an idol, as he fears the possibility of her meeting their mother's fate yet again. Because of his overprotective nature, he gets labeled a "sis-con" by his sister and Co. Even if both don't show it, they 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. Unfortunately, after all is said, they are unaware of who was who in their past lives.

Friends

 * Kana Arima: Aqua met Kana at one of Taishi's movie sets. She was outperformed by Aqua's acting skills and was inspired by it. She later met him at their high school and they became friends with him. He later convinced her to join his sister to start an idol group.
 * Akane Kurokawa: Akane and Aqua met and became acquainted at the reality show, LoveNow. She became the target of bullying by social media, after accidentally 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 also saved her when she attempted suicide following that very incident, saving her from jumping off a bridge during storm whether. He then went on to reassure and silently embrace her after going through such a horrible ordeal. To the public eye, Akane is his girlfriend. However, for a few chapters, it should be noted that he has stated that the relationship is strictly for work. Although in recent chapters, he has subtly hinted that the situation is changing as he promises to fulfil his duties as her 'boyfriend', such as protecting her and ensuring she achieves her goal of beating Kana and Himekawa. Despite initially trying to scare and intimate 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.

Others

 * Taishi Gotanda: Aqua's boss. 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 shut 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.
