Also let us hug Kuroe, Just for affection's sake; also because I wanna see her reaction to a genuine hug.
I think that allowing us to enter their room for a small chat instead of heading straight to their "scene" would be much better, letting us talk to them and get to know them a little better, it would play a little more into the "Dating Sim" aspect of the game;
It would be really fun to learn more about the character's backgrounds and daily life aside from the tiny sprinkles from conversation and the wiki page,
Of course; not like they'll spill it immediately, I think it should be every now and then they could have a little heart to heart as they get more comfortable with the player;
(P.S; Could you add a little bit of brat-taming as an optional route for Kuroe? I just wanna make her mine and protect her and make her feel safe since not everyone is into her kink)
