This is amazing. The MC is the star of the show! I have no problem with him calling the MC dad. I am actually happy he continues calling him that on the contrary. Pil gyun is a complex character and I think I understand what makes him tick. I was pleasantly surprised that Nam gyun actually likes him and lusts after him. I thought it would be one of those manhwas where the MC sleeps with the ML or vice versa purely out of guilt. You can tell he fancies him right off the bat. I think it was in Ch44 where Namwun completely falls apart after Pil gyun leaves him after having found out he was the reason for his dad whoring himself out and enduring the countless assaults, taunts, rapes etc. The two brothers and him were an interesting case. The other hyung was just cool and purely did it coz he was commanded, the other guy on the other hand did it since he loves him.
Ps..Nanmu is the name. Sorry I have trouble remembering names.
