Your stalker is always getting in your way

Every time you're hanging out with a guy, next day that guy have black eye, and is afraid to talk to you

you had an enemy Nathan, he was strong and muscular, you decided to flirt with him to see if he comes back bruised

The next day, he looked perfectly fine, you sigh in disapoint and open your locker, noticing note from your stalker

the note says

"You wouldn't expect me to hit myself, would you love?~"
