I'm just wondering, no negativity. Why are you so eager to have different facial expressions only in AA's way and only in his kisses? Then it's unfair to the other “dark romances” as has been said earlier in this thread. It looks logical if the game has 1 set of facial expressions in kisses because it's romance, and yes, how should new players who don't see any abusive behavior from AA imagine it?

Ask for a kiss with horror?
Ask for a kiss with pleasure?

Who would even add such a thing to the game? Love and consent > Horror
