I'm sorry but it seems you missed something uke was framed into being obsessive and troublesome due to which ml broke the contract but the reason why the contract was made in the first place was uke's safety and ml getting freedom. The stakes are to uneven and unfair. Now that the contract was broken and uke fell into danger and then this mf ml comes and act all concerned when he didn't even question if uke is being framed or not and now that the brother also revealed why their contract worked in the first place so ml being concerned seems to uke that he is trying to just selfishly get a way out for himself with no care towards the uke.

Yigon never knew the contract benefited TK; from the beginning, he only knew she was "helping" him by keeping him safe in exchange for his body. Only now does he discover that he never kept him safe because he thought Yigon was crazy, taking advantage of his body and using it to make a deal with his grandfather and necer told him. Taekang isn't much different from his brother.

Because the ML lied to him and took advantage of him, manipulating him into thinking he’s the only one desperate for the ML. so he feels like he has to obey the ML’s every whim, even when the ML threatened him for his first time. The ML could have made it a fair, mutual deal between them, but instead he twisted it to make it seem one
sided. A one sided contract
Wouldn’t you be pissed if you were lied to like that?
Erm but why is the uke upset abt seme’s intentions? They’re in a contract after all?
