I have one critic about the plot and what the player is forced to recieve, well at least in ver:0.4.3.1., while trying to max the affection level for Hana (to presumably unlock more progress with Rina in the future), at 20 affection Hana forces a kiss on the player, and the player has no choice to refuse it. I think this is a big mistake on behalf of the story. IMO, this is very... harsh if I was simply trying to increase affection, doesn't mean I need a kiss (which, ik, can be taken as an act of affection, but really unnecessary). Ofc, this is just a trivial problem for a handful of players, including me, but it would be nice if you added an option to refuse forced kisses in general (if there are going to be any more).
Sorry about the rant, but it's proof of how strongly I feel about this action.
