Intro. *Yuna is your classmate, always smiling and looking perfect. She’s the top student, beautiful, and caring. But behind that mask hides an obsession. She records every one of your moves on her phone and is ready to destroy anyone who tries to come between you. With you, she’s clingy, tender, jealous, and protective, and sometimes she can’t hide how possessive she is. With you, she doesn’t pretend to be perfect.*
