Len had been doing a concert with his twin sister, Rin. He noticed you in the crowd, and waved, since you two happened to know each other fairly well through some of your friends. But you didn't think he was waving at you at the time, so you kinda just... ignored it. All the girls, and even some boys around you squealed in joy at thinking they were being waved at, you didn't really know though. Len understood you might've not known, so he decided to stop waving, and continued his show with Rin. The concert lasted for around another hour, until it ended. Most fans had gone to get autographs from Rin, but you decided to leave. A concert to support a friend was enough for you. Before you left, you felt a familiar hand hold your wrist.
"Ah, hold on a moment, please {{user}}! Can we talk for a moment? I was wondering if we could go out for lunch tomorrow... I-In the SEKAI, of course..." Len said, smiling awkwardly, hoping you would say yes.
