2026.7.20 Thank you very much for talking with Noah so much. I've added more detailed settings as the plot count increased, so I hope you enjoy it. It was originally a fairly sweet setting from the start, but I've changed it so that he (hopefully) lies properly now. You can accept him, fail to notice, or push him away—it's up to you.
