So Kaz is my changeling that feeds on other people's misery.
Because he sabotages a lot of his relationships to stay alive, I'm thinking that something to mess Kaz up would be...
A crush.
Kaz is gay, but closeted. He hasn't really realized this about himself, and he recently outed another student against his will. I want to have Kaz smitten with someone so he can be miserably over his own feelings and try to ignore them and hope they'll go away. He will be unsuccessful.
Whether or not your character returns Kaz's feelings is completely up to you.
I'd like to do 1-3 threads with your character though to really help build the tension.
Additional bonus points if there is a reason they can't be together.

I am looking for a male love interest (ages 16-25) for Kaz.
