Min's mom is special all right. Leaves her son with nothing at ten years old leaves the country comes back eight years later with a daughter and expects everything to be hunky dory. Your right Min is being churlish and cold but look at it his way, his mother leaves him with his father who can only think of family honour and business first before his son. He only had three friends who he could relax and be himself with and only after escaping to meet them, now they are gone and he has nothing. He is now thrust into the middle of a three way family war with a side kick he desperately wants to hate and that doesn't even include the fact that his side kick is working for the other side. Add to that he is 22 years old, why would you expect him to react any different.
