Keep in mind it's just a prototype. There is no adult content for now (except a nudity scene in the shower and a spicier in bed), just the introduction of the characters and a few things about the mechanics of the game.

Note also that the current prototype will be basically the prologue of the full version, so it's very linear. However, in the full game the player will have complete freedom to do whatever he wants during the morning / afternoon / evening of any day. It will look like Solvalley School in that point, where the player can explore the map freely without having to follow a pre-determined story.
