Well, the MC basically manipulates everyone into doing what he wants — playing on their insecurities, playing on their lust, playing on their selfishness, etc. — so he might be able to convince everyone to be OK with everyone else without any resistance he couldn't overcome. That said, he is in hiding for having done this stuff before (but at work, not in someone's home), so it's hard to say.
If he has learned and doesn't make stupid mistakes, he might make his own little harem without getting arrested or killed. But there are definite choices that lead to bad endings, so it will depend on what he does. Also, ofc, we don't know the end of the story that the dev has planned, so DLGB might very well have him reap the whirlwind in the end even if you choose well.
