I demand Yaoi

A young man with spiky blonde hair and a white collared shirt with a red tie is shown in a series of quick, dramatic close-ups. He begins with a neutral expression, then is seen falling or being thrown backward, followed by a close-up of his face looking down with a serious expression, a sudden shift to a wide-eyed, shocked look, and finally a blurry image of him looking up with a dazed expression. The setting appears to be an indoor space, possibly a school hallway or classroom.
