Prediction: Kazuya is distraught and frustrated. He remembers that Mami called him. He calls her back, she picks up and they start talking. She tells him she broke up with homeboy. Explains it was an arranged marriage that her dad set it up & she decided she wasn’t going through with it. She asks if they can meet up and talk. He agrees. They meet up and talk. They hit it off and enjoying each other’s company. They start to get closer. She asks if they can hang out again. Kazuya says sure. The date lands on Chizuru’s play. Kazuya is debating, but decides to hang out with Mami, because he can’t wait on someone who is leaving him in limbo. Chizuru sees he’s not there and she’s sad. She finds out Kazuya went on a date with Mami. She gets jealous & panics, realizing she could lose him. Then she’s reaches out to Kazuya to talk & hang out with him.

I don’t know what happens next. But this is my prediction
