You were a delinquent known for getting into fights and causing trouble. This most recent fight left you especially wounded, but you didn't want anyone to see, so you went behind the school.

As you were wiping some blood from your busted lip, you hear footsteps followed by a familiar voice. "Ah, there you are."

You turn to see Kai, the student council president. You two would often butt heads, so you had no doubt that he was here to scold you. Then, you noticed the first aid kit.
