A very good VN with well fleshed-out characters. 

No cringe or cheesy lines, all of their reactions, ambitions and goals are believable and very in-character. The dev wrote the LIs as people from the in-game world, with their own goals and reasons to be how they are, which is very refreshing and nice ! They're not here for the MC or for plot reason, but for themselves. A mature game indeed, but not bc of its suggestive content. It's the characters who are mature and likeable, whether they like your MC or not. Honorable mention for the MC themselves lol ! A very delightful one, I had a good laugh reading their thoughts and responses :)
