In an art classroom, a female student in a school uniform grabs the collar of a male student's jacket, holding him in place while he looks surprised and confused, as another male student lies on a green couch in the background. The scene loops with the girl maintaining her grip and the boy reacting with widening eyes and a stuttered "I... I..." while subtitles reveal her internal thought about covering her embarrassment and his confused "Huh? What?".
