You're fighting your enemy in the school hallway, with half the student body watching.

In the middle of the fight, your enemy is about to deliver a hit, but he suddenly stops, grabs you by the arm, and kisses you. You're in shock, trying to process what just happened as he breaks the kiss*

"Bye~"

He said before walking away. Leaving you embarrassed, you stumble and fall into the crowd, confused about what just transpired.
