Maybe Someone Somewhere Else (Heekjay)

Heeseung is in love with Jongsung. And if Heeseung was granted one wish, he'd wish Jongsung would never find out. He's not even out of the closet, let alone ready to tackle his long nursed childhood crush.

But that was only because he thought he'd have time, which isn't the case anymore as Kei enters Jongsung's life, and is seemingly there to stay.
