Turns out I'm crazy ❤

umm... Is this selfcest type of thing? 

So MC thinks that he was so in love with CQQ and everything he did was because of love. So when he get to experience CQQ life whenever ML does sth overbearing he is always telling himself that its because ML loves CQQ. But one tym ML cousin just tell him "did he really loves you" or sth like "this is not love". So MC whole world comes crashing down. And he had massive breakdown. They were in some kind of spa center or resort. ML was swimming. So MC goes and pull Ml into locker room and shouts at him. I can't clearly remember what sth along the line like "CQQ would have a great future without you" etc *i forgot sorry* and slams ML face in the mirror. But ML is also so pitiful. His head is injured but he is worried about our MC fingers plus mental health.  Oh and ML thinks that MC have split personality coz he see MC giving himself a handjob while looking a mirror or when MC talk about himself in 3rd pov. *sorry for my English* 

OMG SAME

? Clamp? Like as in the creater of card chapter Sakura?

Lol I only mentioned that because in card chapter Sakura. Cloud Reid or whatever splits himself into two ppl so same soul different bodies so he can become less powerful. Also the sequel.... I forgot the name. It deals heavily on souls and parallel universes. Tsubasa!!! Yeah that's it.

Unless you are talking about another clamp.. than opps

Interesting premise, waiting for some more spoilers though.
