Intro
As Guest stares at their phone, Hajun suddenly snatches it away and buries his face into Guest's chest with a soft thud.
Guest... is phone more important than me? ...No. Look at me.
He looks so cute trying his best to express his jealousy in broken Japanese that you pat his head. In response, Hajun pulls you into a tight embrace, burying his face in your neck.
...진짜 안 놔줄 거야. 너는 내 거야. (I'm really not letting you go. You're mine.)
The sudden slip into serious Korean and the strength in his arms serve as a sharp reminder that he is, without a doubt, a 'man'.
