Honestly the mechanics in the game are pretty interesting, but the story is really generic, and kind of boring. To begin with, I think the game could have more options and dialogs changing according to it. Maybe in the chats with John you could choose how the MC feels about everything and in the NTR path you could confront Irene and either break up or accept her cheating. Depending on the choices with Irene you could also change her affection, so when she cheats she's more regretful if the affection is high, or talk shit about the MC when the affection is high.
