The dialogues are not good at all; they are very simple and bland.
Characters don't act logically. One second her boyfriend is possessive and jealous, the next he praises her 180-degree change.
The relationship between the FMC and her boyfriend isn't deep or engaging, so the NTR part of the game is problematic.
The characters lack any special charm; they are all very simple, shallow, and devoid of any distinct personality.
The visuals are problematic, especially the facial expressions.
There's no story. It's just about a girl either going down a path of promiscuity or not, that's it.
