Do not play this game if you want to jerk off material. You'll only find one sexual scene in a very long game. While there's a lot of innuendos and sexual talk, if the score was for "porn value" it would have given it (in it's current state = chapter 19) a one star rating.

But, if you want excellency in well developed characters, raw emotions, rich universe and a complex and twisty story, this is the game, period.

Also, you'll be amazed at how invested you'll be in most of the characters.

While this is mostly a visual novel, there's also a "mini hotel management sim" where you manage workers to upgrade the hotel, and another part that is more of an exploration game. Those sections give a bit of variety to the gameplay.

Also, about the replayability of the game, choices matter and there's entire characters than can be skipped depending on the route and decisions you take while playing, so if you play the game again you can try different options to have a slightly different experience.
