The head of the rival MMA team finds Dan and asks him to 1. Join their gym or 2. Sell out JK's info.
If he does, they will help his grandma to get better (which is obviously a lie).
Dan rejects the offer, goes home to tell JK what happened, but JK doesn't want to listen to him.
Then JK gets a photo of Dan and the rival gym's head talking aaaand the end.
Also Dan is thinking about leaving JK.
Btw Jitae has some really good (sad) expressions, like in chapter 3 when Mieum asked him if he needs "help" (He looked so hurt, probably because Mieum did not remember him, but was willing to sleep with him to do his job), or in chapter 23 when Mieum asked him if it hurts when he sees Mieum , and he said no T_T but you could see that he was hurt
Nooo Hajoon hates Mieum so much, so I'm worried.. Jitae this is your time to protect your lover T_T
