"I love you"

A young man in a school uniform makes a finger gun gesture, then appears in a classroom with his hands clasped, followed by a scene where he stands in a hallway with his hands near his ears as other students are marked with X's, then a close-up of a girl's plaid skirt, then a close-up of the young man's wide eye, and finally a close-up of his face screaming. The setting transitions from a train or bus interior to a classroom, then a school hallway, and finally a close-up of the character's face.
