At zero.

A young man with dark hair and a black and white collared shirt has a tired, annoyed expression that shifts to a slight frown. The scene cuts to a young woman in a red bunny costume with long brown hair, who jumps onto the man's back from behind, causing him to scream and fall forward onto a desk. She then stands triumphantly with her arms outstretched, while he remains slumped over the desk, still screaming. The setting is a classroom or office with a whiteboard and a window with a blue curtain.
