Well, MC did say here that it's only within a game's fiction that a "character" would conveniently act like the villain. In this scene they both "confirm" from each other that they see the current situation in the same way, which is that this is reality for them--not a game anymore.

What I'm curious about is why she has "Estrus" displayed on her status. MC declines her saying he doesn't want to give Buta-O's virginity to her because they both know that Buta-O has a relationship with the other girl, and MC is just "possessing" Buta-O's body. This confuses me. So is MC going to just stay avoiding all the girls until the end of the story because he's not really "himself"? Or is he really Buta-O as well, and he just can't accept the truth yet? Seeing as the novels show MC being Buta-O permanently, going by the illustrations, I find it hard to believe they're going to keep pushing the girls away for the entirety of the plot just because MC thinks he'll have to give Buta-O his body back in the future. To me, it's either MC and Buta-O are one and the same. Or they separate bodies soon and go from there, which ruins the entire premise.

That status of hers is similar to that of MC “Gluton” (makes him insatiably hungry), apparently all “reincarnated” people have some kind of curse, that’s why when he noticed the status he says “as expected she has it.”

MC thinks he is only “possessing” Buta-O’ body ’cause he can still “hear” his feelings, especially when is about Kaworu (childhood friend), in the novel whenever the MC thinks that she would be happier away from him Buta-O refuses to hand her over to someone else, the MC doesn’t care about the bullying but whenever it starts Buta-O fills the MC’s mind with negative emotions.

As for the girls, none have shown romantic interest in the MC so far (currently in chapter 132), mostly curiosity, Kaworu is stuck with the idea that she is tied to him because of the contract already mentioned in the manga. The MC states that he respects Kaworu for everything she is forced to go through in the game but that’s it, he only had one character that he really liked in the game during the time he played, but he doesn’t get close to her either.
