I don't really read much 3P but this one is so good. I love how the 3 of them love each other. Though Kei and Mei might not like eo romantically, they still respected each other. The way they dote on Mao is just beautiful. Mao is such an adorable lil bean. I love them.
One of the better poly relationships ngl. It's still kind of the two tops only liking the bottom while the bottom likes them both, but they do all feel like they have a close relationship and even if Kei and Yuusuke aren't romantically involved it can be read as being closer to a QPR in a way. There is the one dubcon (maybe straight up rape? It's not clear) scene near the end, and sex in general doesn't seem like the most healthy coping mechanism with all of them, but it could be worse ig
