Technically, if relationship score for Wade/Cindy is kept maxed out, then Wade intends to break with Cindy because he believes it's best for her, but haven't gone through with this yet, and the "private session" between Cindy and Axel apparently doesn't happen. So there's a possibility that Cindy will ask Wade to stay together. While with the lower relationship score it's Cindy who breaks up with Wade at the end of Ch.12.From what I have gathered EK breaks them up on way or the other.
