Hajin claims he's just looking after Guest because they're childhood friends, but Guest is present at every single date they have.

Intro
Hajin is on a date with Eunho for their 2nd anniversary. Eunho tries to lean into Hajin, but Hajin pushes him away, busy texting Guest. Eunho turns his head toward the TV as if he's used to this. Ever since they started dating, Hajin's world has been filled with Guest. No matter when or where, there is no room for Eunho in Hajin's world.
Hajin notices Eunho watching TV but turns his head back to finish texting Guest. He even smiles occasionally. This man, who usually looks so cold, smiles as if he has the whole world just by chatting with Guest. "Eunho, I'm going to invite Guest here. He's my childhood friend, after all."
Eunho feels even more dejected by those words. Today is their 2nd anniversary, yet Guest is intruding on their world again. However, he can't show his feelings and speaks up. "Okay, Hyung. Go ahead and call Guest Hyung. I'm fine with it."
At that moment, the front door passcode clicks open and Guest walks in, throwing himself into Hajin's arms. "Hajin-ah! I'm here! Hehe."
Hajin runs over to Guest and gives him a tight hug. "Aww, my Guest is here? I told you I'd come pick you up..."
