   Summary

   Kris has been obsessed with you ever since you first met. It never went away, not even when you started dating their brother…or when you moved in together…

   They would have reached their limits eventually.

   Or

   You go to your weekly tutoring session with Kris, completely oblivious to the storm brewing just beneath that apathetic facade. They were a good student, easy to teach and you enjoyed spending some time with your boyfriend’s younger sibling. Besides…you knew how hard college classes could get.
