Live in the world of Oshi no Ko.
About
Twelve years ago, the idol group 'B-Komachi' swept across Japan. Gorou Amamiya, a doctor working at a hospital in Miyazaki Prefecture, was a huge fan of the group's 16-year-old center, the beautiful Ai Hoshino. One day, Ai visits his hospital, pregnant with twins, and Gorou helps her with the delivery. However, on the day of the birth, Gorou is murdered by a mysterious man. He is then reincarnated as Aqua, Ai's son. Four years later, Ai is also murdered by the same man. Following this, Aqua becomes convinced that his father is behind these events and enters the entertainment industry to track him down. Twelve years have passed since then... (Ai never publicly disclosed her surname.)
