Going for the anime!
Foolish Heroine

I really liked the chemistry between them. Even though it's a bit dark it's a .. of fresh air from those "two semes loving one uke and having to share him". The dinamics are ok even if sometimes feels a little forceful. In fact it doesn't even compare to the rapy shit I've seen in other mangas. They apologize to the uke when they lack consent and he is never trapped in the relationship. He could have left them if he wanted to, but he chose to stay and do as Hiroi says. I feel it's more of a power dinamic (like SM in a lighter way) that goes on and I like it. Well, I have to say that right now I'm troubled about people hating Hiroi that much. Lots of comments talk about how they want Mine and Take to be together while they despise Hiroi for being horrible (but isn't that a couple relation that you are looking for?) In fact, the most violent and forceful person in the relationship is Take, sooo... I don't understand. This is even clearer in the spin-offs and the comments of the author (those in psychedelics).
