trying to refind a story ...... on her wedding night she is murdered by the groom he even cuts out her tongue and reveals he is her half brother and her best friend is pregnant by him. as they walk away she sets off the bomb they planted killing them all, next she wakes up in her old bedroom and realizes she is reborn and gone back in time and decides to change her fate. Not sure if it's on this site

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)
