Uea and King are the Male leads, King seems to like Uea for some strange reason. From the very beginning and for no real reason Uea is rude and obnoxious to King, most normal people would take the hint but King kept trying to be friends. Half way through the first episode he gets lucky, Uea gets very drunk, King drives him to his apartment and rapes him while he is drunk.
Uea wakes the next morning upset and leaves while King is still sleeping, I actually thought that later they might argue about consent, about drunk sex , but no! King couldn't understand why Uea was ignoring him ( buggering him while he was drunk might be a reason) and Uea was just hiding. They finally talked about it and Uea said it was all his fault and to forget about it , King seemed upset by this because he really likes Uea ( raping him is a sign of love)
I don't want to say that there are different grades of rape but it always seems worse when they justify it by saying he only did it because he likes him so much.
Thai BL did move away from the drunk rape formula for a while, they decided to go with a controlling Dom, manipulating, coercing and blackmailing a mentally challenged younger guy formula , but now they seem to have decided drunk rape works better.
