Hi, I love your game, I wanted to mention I came across a bug that happens really really rarely and I've only seen it when managing the boutique.
You will sometimes not get the points added to your stats, and again, I've seen this happen only four or five times through my playthrough (I'm at the second interval for Zane's PoV because I want all his endings so I am working my booty off to get them).
I though the info would help you out should you make any updates, or continue your journey to make a stat raising otome which I would love to see done!
