How much content are we going to miss if we reject the mind control drugs? I love that you've given us the choice, but if most of your content is dependant on it, then I'd probably just not play.
It'll be disappointing as fuck if the only reason you manage to fuck the brother's girl is because of drugs.
PARE system is cliche and ruins everything you set up in day one. You may want to telgraph these sooner so they don't feel as sudden/jarring. Having all the first day interactions rely on the regular charm approach sends the wrong message. If you opened with PARE, I would have stopped playing before getting invested.
You've now got charm, drugs and abuse of authority. These approaches all fit different MCs. There's no reason for one guy to use all these approaches. PARE and drugs are definitely going to be easier to write than human interactions but it just feels like a waste. Morgana was already breaking after one conversation. Using drugs makes that entire swimming scene meaningless.
