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 good friends. He later convinced her to join his sister to start an idol group.
 * Akane Kurokawa: Akane and Aqua met at the reality show, LoveNow. She became a target of social media for accidentally injuring Yuki, another actor in the reality show. Aqua stayed up nights making the video that would go on to redeem Akane's reputation. He also saved her when she attempted to suicide following that very incident. Currently, Akane is his girlfriend. However, it should be noted that he has stated that the relationship is strictly for work.

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.
