There is no other word to describe him, rapist. He abuse Dan in every way: physically, emotionally and psychologically. I agree with you in the redemption arc but Jaekyung is such a red flag. I will not care when the author tells his sad back story. No past trauma allows you to treat other people like he does.
Dan is developing a serious Stockholm syndrome too...

Maybe have a civil conversation with them? They will tell you. People are allowed to like/hate/love/dislike him. You hate him. I think he is dull. We need to respect others.
Also, your pov is rape. There are many people who sees it as sexual assault and abusive. It is close to your pov. It is just Jk is a sexual abuser. He is still toxic and doesn’t excuse his behavior. His behavior is disgusting. He needs to treat Dan better. Team Dan here! Please don’t attack me. Maybe if you politely talked to someone who loved Jk. You may get an answer.
I can tell you my friend is disappointed in this story but the quite and reserved side of JK reminds her of her Korean boyfriend but she’s doesn’t like him. There are things that people like. You just have to have a civil conversation with them. Maybe has a bad impression on him and some of it is falling for his facade.

He hasn’t beat Dan. He hasn’t confident Dan. I could go on. This is a dull toxic story. There are worst ones where the seme would choke the uke until the uke passes out. This is Disneyland. He could be worse.
it isn’t Stockholm Syndrome. .
As we know, Stockholm Syndrome is a coping mechanism to a captive or abusive situation. People develop positive feelings toward their captors or abusers over time. This condition applies to situations including child abuse, coach-athlete abuse, relationship abuse and sex trafficking
This isn’t the right type of relationship abuse and if you look at psychological causes, signs and symptoms this story doesn’t fit.

The original Beauty and the beast is Stockholm Syndrome but the Disney’s version isn’t. https://scholarsarchive.byu.edu/cgi/viewcontent.cgi?article=1460&context=criterion#:~:text=The%20original%20Beauty%20of%20Beauty,syndrome%20have%20all%20but%20vanished.
Toilet terrorist likes to add it is trauma bonding but I don’t know about that.
