Two anime characters sit together in a dimly lit, enclosed space, one with long brown hair looking down while the other, with dark hair, raises a hand to their head. The scene cuts to an overhead view of the pair standing on a narrow walkway, then shifts to a bright outdoor setting where a character in a white shirt throws a backpack at another character in a black shirt, causing him to stumble backward, while the character with long brown hair watches from a seated position. The sequence ends with a close-up of the brown-haired character's wide, surprised eyes.
