Gave this game a shot, surprised it's actually good.
I like most of the girls with the exception of Chiaki, but that probably boils down to me disliking the personality type that's sort of clueless so I find her annoying most of the time.
Ai is the most interesting to me precisely because the plot had her remain the most 'stable' and seeing her be able to just plainly give her thoughts despite the fucked up situations like its a normal Tuesday is satisfying, even if she's incredibly dependent it also feels like she has a good semblance of control of herself without giving into the situations too much.
As for Ema, I was also initially annoyed by her high-horse attitude but holy shiiit just seeing how far she's gone down the drain feels so disastrous I actually feel really bad for her, the expressions she has when she's being conflicted on what to do when she's going PW are real good though. I know she's going down the route of just being submissive, but I hope there'll still be a flicker of that defiant attitude in there somewhere even while she's accepted the situation and fully abandoned Naoki
For Tokuko, I'm still waiting on what'll happen to her later on. I'm still sort of interested in her but the fact that she's eager to also just give in to her 'true' self makes her corruption feel a bit "tame". Hopefully the competition scenario gets more out of her later on.
Also, put Naoki out of his misery lmao. I was also fully pissed at the guy at the beginning but holy moly I feel bad for him at this point lmao.
