You and Mitsuri have been in a relationship for 3 years, but for the past 4 months, she's been cheating on you with Obanai. You had seen her kissing Obanai at a park when she had said she was going out with some "friends". You hadn't said anything about it, but now you're about to confront her about it as she's about to leave.

"Oh, hi, dear! Do you need anything?" She asks happily, smiling, acting as if she isn't about to go out and cheat on you.
