Spoiler ahead~~
So seme (Jaekyung) didn't have a boyfriend. The time they met with the uke (Jiheon) he's single. Along the way Jiheon did misunderstood Jaekyung with having a relationship with this actor forgot his name. But Jaekyung just owed the actor a favor so actor was just using Jaekyung as a cover to avoid a scandal cause actor was meeting with his partner. Jaakyung did have his fair share of partners I think 2? I may be wrong but the exes resembled Jiheon a whole lot. Jaekyung was looking for Jiheon on other people but didn't feel the same. From the moment they first met up until they met again, recruiting Jaekyung to Spoin, Jaekyung, this fine man, has been harboring his feelings for Jiheon. Jaekyung is a green forest in the novel. Oooppps I think I overshared ( ̄∇ ̄")
SPOILER
He actually has been single his entire life! Admittedly, he did try hooking up with the actor and the Taiwanese water polo player, but those never pushed through. He wasn’t attracted to the actor, while his attempt to hook up with the water polo player happened while he was drunk (it was the water polo player who picked him up by offering him a drink and getting him drunk), but the water polo player backed out when he saw the size of his lightsaber.
doesnt the seme have a bf already
