The only one being groomed in this game is the MC. Becca is the one doing the grooming.I like the game for the most part. I could understand the MC being very reluctant and that makes a ton of sense. The only issue I would really have with his fears outside of just it being morally wrong, would be the effect it would have on reputation. The only legal reasons he should not engage with them is if he thought that they may lie to the police and say he did assault them as a minor. Besides that though people would rightfully think him a creep to sleep with girls he helped raise. It is already considered pretty bad to sleep with a girl half your age... but someone you actually raised and possibly groomed? Oh yeah you would be a total outcast in the community. So for being something like a realtor? Your name would get dragged hard, hell your ex could possibly try to do that even without you doing anything though.
Besides that stuff though the renders and stuff look good and it is an interesting take being the target of corruption.
