This was sudden and... kinda pathetic and anticlimatic? A typical "follow to the transport and shout don't leave me"? They went for passionate and was underwhelming instead... I was hoping for Kim Dan getting a text reminding him what they said at the beach, that he'd support him no matter what. Or granny going through an emergency an him turning up to support Dan. Not this... Basic abuser manipulation tactic of crying while asking the abused not to leave them? That's more of a red flag in my eyes, he's putting his suffering on Kin Dan, like "if you leave me now my life will be over". Abusers do that...
Such a pity, I actually liked the way it was going, emotionally, in their development... With JJK realising how badly he treated him and trying to make ammends not asking for anything in return...
