You or (crush) is a yandere. This doesn't have to be a high school setting but it can be.

Scenario 1: You are getting ready to head home from school when you hear voices in a janitor's closet near your locker. You glanced around to make sure no one else was around before going to open the door, only for the voices to go quiet and a thud to be heard. You quietly opened the door only to see (Crush) standing over what now looked like a corpse of someone you talked to earlier. You froze before quietly backing away from the door. Do you get away without getting noticed? If you do you tell anyone about what you saw? (Can be reversed.)

Scenario 2: You were at home, getting ready for bed when you heard something in a different part of the house. You didn't have any guests over at the moment of course because you were going to go to bed.(If you have a pet then the pet is in the room with you.) What do you do? (Can be reversed so that you're the one sneaking in.)

Have Fun!
