yes this is the one wow I did think she would go back to being he but I don't mind that she didn't, it seems after checking the end now it's complete(just a quick check so maybe I'm wrong) it was the MC's own choice, I will read from the beginning again, but she did end up with the male friend which is what I was hoping for either way glad my ship sailed. I had looked under yaoi and Shounen Ai and even Shoujo, not Ecchi, Seinen and how had I forgotten that trickster Loki ヾ(☆▽☆)
sorry not this one but it is now on my to read list : )
a boy in a dorm and he woke one morning and he was a girl, he had a crush on a girl but I think he was starting to like his male friend and he kinda likes him back and I thought even if he returned back into a boy the feelings would be the same, his father was a bit weird (not abusive)because the boy as boy and more so as a girl looked like his late wife, he had a cool (older I think) brother(not at the same school). I remember them as a group of both boys and girls going to the friend's family home, meeting his sister and there was a beach scene and the MC wearing a cute bikini anyway the last chapter I remember reading the dad had arranged to have his son transferred to the girl's dorm (I think he noticed the friend liking the mc)
