You really think he means what he said? Most of his thoughts are him convincing himself but his actions say otherwise.
He does want Danny to come back for his Jinx, but like the first few episodes, it's up to Dan. He won't force him if Dan has a choice. The only time he forced him to stay somewhere was because Dan was pretty much homeless.

Thats why jk is trying to get through kim dan from getting in his grandma good sides to take back kim dan
Since jk wants to use him so he can be in a better condition fo his next boxing match
Also the biggest reason why jk wanted to come back to see kim dan was to have sex since his sex was ¨good¨
And just maybe most of jk thoughts are him convincing himself that all he needs kim dan for is sex but his actions say otherwise
Than why did jk ask for sex in return to repay for his debt???
he only wants kim dan since it was his comfort zone and now that kim dan left all hes been doing is drinking

Yeah, don't take everything face value. ( ̄へ ̄)
He hasn't mentioned "sex" since he got there. If it's for his Jinx, then he can literally have sex with anyone, yet he went 2+ months without sex because he's only thinking of one person. Dan's presence has always eased Jae (evidence: when Danny left, Jae started drinking and having insomnia. When he moved closer to Danny, both drinking and insomnia stopped). He even put his career on the line without a second thought just for Danny to come back with him. He panicked when he saw Danny walk into the ocean and wasn't responding, and despite a bad shoulder, he carried Dan to the hospital and stayed until he woken up. Don't forget he put a lot of money down just to find Dan. Yes he did "initially" go see his grandmother to get to Dan, but Jae has shown to gave respect for the senior citizens and seems fond of Granny. Even when he first met her, he didn't have to go to the hospital or anything, but he did.
If you look at epsiode 4 and epsiode 64, there's a contrast. Similar positions, different meaning (one screams lust, one scream intimacy). And if I remember correctly, Dan requested (as a "wish") if Jae could not cum inside or at least tell him to which he said "no." And yet about a few episodes later, he let's Dan know he's about cum.
However, I get it. Jae has done unforgivable things (pouring our American cola? The audacity!), but he's done other things (giving Danny his jacket, paying his loans and Granny's bills, giving him a home, etc).
This blind hate will make it harder for readers to finish because these 2 are end game. I'm unsure how people will cope.
kim dan grandma is thinking jk is there to help kim dan but jk is only there to have have sex with him
