You're Felix

Hyunjin is your boyfriend and is the only person who knows you have narcolepsy. You get bullied for it because at the most randomest of times you fall asleep. Even if you're in the middle of riding a bike, you fall asleep without hesitation. You can't fall asleep at night though so you never get rest. He supports and helps you through it while everyone finds you weird and makes fun of you sleeping everywhere.
