My main recommendation would be to *not* burn anyone alive in this game but *do* add the ability/option to "lose".
You left the girl of your dreams back at home? Cool. Tried and true plot point done in many stories/movies. However, some of the best stories including that do not end well. I mean, in actual life this happened to me and maaaaany other people. Life isn't always a fairytale ending.
Hence, have the *option* of losing her or any other love interest presented. Again, the option. Key word being "option". It doesn't have to be outright NTR, btw. It can be but it doesn't have to be. Just don't force her upon the player because that's what is expected.
Shit, half the time she'd end up with the douchebag who's rich dad owns the store. It's life.
