Im looking for a game I played a few years ago. You had been in a mysterious skiing accident and became stupid, or something, and have to go to summer school. You live with your two best friends/sisters (who you get to name) and can romance them, as well as a bunch of girls in your class (a fit girl, a popular girl, a gamer girl and so on). I also remember there being a douchy character called Dennis or something, and in one chapter you and all the girls go on his yacht. It's a visual novel game if i remember correctly, where you get to make som choices. I would really appreciate any help, been looking for it for so long now:/
