Inroduction :>

So basically Jung kook bullies Jin in their high-school years, he and a member from his "gang" (taehyung) start developing crushes on Jin, fast forward like 5 years, Jin and Taehyung are dating. Jung-kook gets jealous when he sees them together cause he still had hidden feelings for him and tries to steal him from Taehyung... but little did he know someone had been trying to steal Jin for himself as well.
That's as much as I can say. :>
