@ElBichoRaro Frankly I kinda hope Rou gets together with Mao. This story seems to hit all of my usual pairing suspects at once that it really kind of threw me off. Any time there's a genderswapped protagonist, I always end up shipping them with the male best friend since I kinda like how the story frequently unfolds. But Jiu still acts more friendly towards him if at least he's really worried Mao is getting in over his head, and Mao definitely treats him primarily as a best friend. So that ship is sunk. Then we have a sister character, who I also tend to ship when possible. Ako kind of pisses me off sometimes but I can feel where she's coming from. The problem is Mao just doesn't see her that way (and he still believes they're twins), so I can't really see there being a ending involving Ako that would satisfy the both ofthem. Deep down, after getting to know all these characters, I just feel like I don't want to ship either of them.
Rou is a good alternative for me. I can't argue facts, he has a ton in common with Mao and his primary negative trait is so perfectly in sync with Mao that I can't see Mao viewing it as a total negative.
While I feel like this is going to end without Rou getting properly involved with Mao romantically, I wouldn't be opposed to it.
