Very vanilla. I was expecting more of the sister, but she seems like just a backgroud character. Also very easy and short, but that is not bad. Like may japanese games, a little too grindy for no reason since the game can be reasonably finished in 3 hours even on normal mode. Could benefit from having a gallery and some clear indication of the requirements for the scenes. Was also very sweet and wholesome. No NTR or any stuff like that.
