I agree too, I didn't feel comfortable while reading...
it's weird...
it's true that they are the same body with different personalities, but the author made the story as if it was a love triangle...
as if the MC was in a relationship with the ML but he started loving someone else, it felt like cheating..
and the fact that Rei created Kazuha to be the pideal character for him, then the MC started loving it and started thinking that it's okay if Kazuha was the host, it made me feel sad...
because from the beginning no one loved him as he is so he had to create all these characters..
but the MC instead of continuing to help him become one, he started thinking that it's okay for the two of them to stay and continue like this..
so, I didn't feel his real love for Rei and for me the story failed to make me think that they are one person, anyway I didn't feel comfortable until the end ...
Not really sure how I feel about this one. It kinda felt like a cheating story, because of the way the main guy kept getting seduced by Kazuha when he said he loved Rei? Have some shame… it was alright at first, but after realizing who he loved he should have stopped. I don’t know, it’s just a turn off to me personally! Other than that, like someone else said, they focused too much on the curing of DID rather than the actual relationship between the guys. I didn’t really feel the passion.
