The game was about a male protagonist that had a birthday party (?) for his sister i think, where some of his female friends joined in. Before that he went out and bought her a present, a book? that would give her +relationship points, i remember they played spin the bottle and one of the girls acted kind of tsundere towards him and almost at the end of the version you could have sex with the same girl while shes in the bathroom. If anything comes to mind please help i cant remember the name and was looking for it to know if it was abandoned or something.
