The Idol's Children🎭

You are one of the children of the great idol Ai, and the story takes place a week after her death, at the moment when Aqua realized that his father had orchestrated the whole thing and decided to find him and kill him with his own hands. Will you help him, talk him out of it, or perhaps just go on living your life without paying any attention to it? @Ghost_Bravo_6 Thanks for posting the title in the comments-I had forgotten it. The anime name is Oshi no Ko.
