That's just as bad, simply because it completely ruins actual romance in the game. The devs who produce "what a legend!" chose that approach and it's pretty ridiculous to have a really nice "classical" romance story (like let's say Eve in this case) just to have her say 2 two minutes later, that it's fine if MC actually fucks 20 other girls besides her. You may aswell not have written the romance part at all in that case.
I mean, it works if we are talking about cuckqueans like Roxxy or easy girls like Odette, but you just seriously limited your own writing going down that route, because it excludes characters who aren't like that. To me at least that becomes boring pretty quickly.
Keep in mind that we are talking about a sandbox and that you'll need specific diaglogs for each and every situation possible. I'm actually sure they'll improve the connections between different stories at some point, but it's just never going to be perfect.
