This was a much better resolution than I thought it would be. These girls are teenagers stumbling about in the dark and looking for someone else to help them through the night. Shizuka was jerked around over and over and I don't think she realized, really, what she was doing to Mio until she was caught doing the very thing that was constantly done to her. I feel Shizuka can face the future with Mio and a better understanding. I don't think Shizuka cheated, per se, as they weren't going out. But there was definitely a violation of trust and I think Shizuka will be willing to work hard to justify Mio's understanding.
