Daehyun doesn't know that his innocent boyfriend is keeping a secret from him. Though it's no secret that Youngjae is a big fan of TVXQ and JYJ, and constantly fanboying over the formerly 5 members group; no one knows that he's secretly shipping the leader (Yunho) and the lead vocal (Jaejoong) as YunJae couple and is collecting all YunJae fanfictions he come across like every other fangirl does.
That was until Daehyun caught the boy reading a copy of the famous YunJae fic: Thorn Year (가시연) a.k.a the holy bible for all YunJae shippers.
