I was trying to find a yaoi manga that I know is on mangago but I didn't save the name. All I remember is that it had less than 10 chapters. Summary is that a boy got exiled from his family by his grandfather after being framed having sexual relations with men. Next, he has to go to school to have any hope of getting back in. (There is also a leaf confession for some reason.) His ex finds out he was framed and his grandfather apologized and lets him back in the family. It's definitely Japanese.
