Lee never forced himself on Hyungdo, but let's put that aside for a moment and sum up Lee's actions...
He was charmed by Hyungdo and flirted with him to seduce him into being a prostitute. He never lied about his goal toward that end BUT he felt a chemistry with Hyungdo that was strong enough to get him to try out a relationship BUT Lee is a Dom at heart so he had Hyungdo sign a contract to be his exclusive, live-in lover for 2 years. The Clan stole everything but all he wanted was Choi back and he got his ass beaten and his chest stabbed while trying to get him out because he was trying to make good on a promise to give his sub a life of comfort. FF to the present, Lee has an overactive libido but he stayed celibate for 2y, 8m bc he was keeping a promise to Choi. He wants to protect Choi and get him back for himself, oh and he wants some payback from these Clan fuggers. That doesn't sound crazy to me that sounds like karma. Lee did Charlie and others wrong and he paid for it but they went too far bringing Choi into that so Lee is gonna set them straight.

both are crazy for sure, but the bowl cut guy is more mentally unstable while the main guy seems to be more "resonable." For instance, when the uke said he's not gonna follow him, he was able to accept it even though he was struggling at first. Also, you have to look at relationship in both directions. Same action might not result the same reaction. The obvious difference here is that the uke loves the main guy, that's why he was able to forgive him more than the other guy. Just like if a guy asked you out, you would likely to say yes if you like him, but if you don't, then it's likely you would say no. Same action but not the same reaction. Your feeling (or the uke's feeling in this case) is important, and it somewhat determines the outcome too.

Remember Lee warned that his love wasn't the cute hearts and flowers kind and boy does he deliver.
Recap....
Lee flirted with Choi and tried to recruit him
Choi went to Lee for sex but backed out...bc anaconda
Lee was pissed that hyungdo filmed using the expensive buttplug he gave him..he was also jealous about the bj Choi gave Mary...then he found the other porns and he felt deceived by Hyungdo, who refused to become a prostitute. Still the rough sex was shitty of him since it made Hyngdo bleed. But the sex was consensual, not forced.(He asked for consent and hyungdo wanted to have sex BUT he didn't expect the rough sex Lee gave him...Here is the proof ...pages 14-15

He has sex with Choi again with consent but more tender, as an apology for the roughness. He asked permission to keep going and he got it. Choi passed out and he continued...he told Choi about it later when he washed him, then he fed him and gave him a ride home.
He kept Choi locked up for a few days to give him a taste of what to expect as his lover/exclusive manwhore. The sex was consensual but not the confinement.
Charlie frees Choi. Lee pays off his debt to keep Choi tied to him.. He was feeling possessive. He went after Choi and had consensual sex in front of the moneylender friend.
He got Choi to sign the contract which was basically a typical D/s lovers contract. He buys Choi cake and little gifts bc he thought his reactions were cute and then he got betrayed by the secretary.

Bruh I'm not saying this because of your opinion I could care less I ain't tryna pick fights. I'm saying this because of one reason and one reason only...your username. I'm ugly but I blame my creators.
ALsO iT waS a JoKE...SUPRISE. I rarely take anything serious I'm bulshiting your username could be dick juice and I wouldn't give a fuck..
So.....these crazy eyes Lee has been sporting.....are they not the same as the crazy perv. This mother fucker is just as crazy as they perv. The difference is, is that MC loves him. But I'm sure if the MC denied him just like he does the other guy, Lee would be just the same or even worst. He's already forced himself on MC, can't remember if he hit him or not, but I'm sure he would or even kill him if shit hit the fan. I'm just lost for world. Lee is turning into Charlie he's just more dangerous.
