The MC is truly in love and says he would never betray her or be with anyone else, ever. But Lo and behold, it turns into a harem. Love interest nr 2 keeps nagging MC, telling how much she loves him, and he just caves in, totally going against his “pure” and honest character. MC says that he might never love Nr2, but she can at least “be with him and Nr1” What the f**k!? It seriously doesn’t make any sense at all, I guess the author wanted a threesome, and this was as close as he could get.
