I made a mistake by choosing Kate's route first.. and now I can't do another route.. like Violet's.. I ended up cheating and I felt guilty because of the dialogue I just didn't continued the route.. I really fell inlove with her character...
Ouch, we don't let them go easy. I'm glad that you've enjoyed the character so much that such a reaction was had. In the next run, you can just be friends with Violet or Kate which doesn't have any harsh guilty feelings.
