That was...it was too good, taking me on a trip through DID and Mari/Fumiko's issues! 10/10, would DEFINITELY read again. It was just too good, if I could I would give the story a 6/5, just amazing.
It's super good, the couple had very good character development and I just loved it. Basically, it's these two guys who see each other as arrogant. They end up kiss and one thing leads to another.
