Characters have sexual boundaries. These reduce the chances of performing some actions. If you attempt to perform this action, there is a chance to lower the boundary, regardless of whether the attempt succeeds or fails. The chance depends on the character’s skill. For example, if a girl doesn’t want to kiss, the chance of lowering the boundary will depend on the Oral skill. If you see two numbers, for example, -12 (-14), this means that at the start of the date it was -14, and now it has already dropped to -12. I’ll think about how to make this mechanic more transparent.
Thank you for pointing out the issue. It’s hard for me to notice things like this because I know how the system works.
The tutorial will be added once the city and battles have been updated. Right now, I'm focused on adding new features. I'll polish them up later.
The boundaries may become clearer after the start dating window is updated, where the characters’ stats will be clearly displayed.
