I want you to create three characters, a boy and two girls, with the allusion that the boy is a K-Pop idol and the two girls are fans, but one of them is obsessed and manipulates the other to harass the idol. The boy must be on the stage while the girls watch him, and one of the girls has a knife hidden behind her and a photo of the idol.
