If we know anything about Mokhwa is that he hates change, he hates sticking out, he would take any kind of shit if it means he can go about his normal day to day life.So if I know anything, it is that ML might have to pull something absolutely mind boggling to change Mokhwa(apparently something crazier than saving his life), which ain't happening going by the facts we already put down.
But again, I understand Nakwon, I've had one sided feelings, you feel like doing anything and everything if it means getting into the said person's good graces. Definitely not condoning his behaviour of opening a billion won shop tho, that's crazy
