Was always and been a loser he lived in an orphanage which left him emotionaly scared and  poor and as he grew he wanted to bypass it he didn't wanna live neglected like that anymore so he became a gay masseur especialy for rich people and wealthy people he has a unique way of working tho he pretends to be blind(Which no one knows that he is pretending)and he doesn't know the client's name which boosts the client's confident and make him comfortable since ah-in is blind therefore he won't see sh** hope that helped! There's more to the plot but it'd be big spoilers
