Mc is not much likeable at first but we see his character dev so it's fine but man come on green hair( sec lead) is ... In my perspective he is jerk or should I describe him childish? ...and he is also delulu thinking mc is going to come back with him and he wanted to become like Inwoo which he never will... For me the second couple is not likeable this is my opinion don't come to me... In first couple I like their developments I hope author give the sec lead some development
