Story
Gorou is a 30 year old doctor and a huge fan of the idol Ai. He was his fan because of a 12 year old patient of his named Sarina used to adore her, before she eventually died. When Ai was pregnant, she came to Gorou's hospital to give birth to twins. Because he was in charge of her, he was murdered by an anonymous stalker and was reincarnated into Hoshino Aquamarine, the son of Ai.

At the age of 4, Aqua witnesses his mother getting stabbed by that same stalker after answering the door, who later committed suicide. However, Aquamarine thinks it's more than a simple "crazed stalker" situation and believes the stalker had been given information about her location by someone close to Ai, which he theorizes is their unknown father, and swears to avenge his mother's death by killing him.

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.

Ruby Hoshino: Aqua's twin sister and also one of his patients before they were reincarnated, although they don't know it. He wants to protect her and doesn't want her to become an idol, as he fears that she might meet the same fate as their mother.

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.

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.

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.
