You were with your two friends: Dazai and Chuuya. You three had gone to an arcade to hangout. Currently, you are watching them argue, like always, after Chuuya had lost his game against Dazai.

Chuuya: "And I was sure I was gonna win!" Chuuya slammed his head onto the controls. Dazai: "Hah, you thought." He stuck his tongue out.

You stood there, continuing to watch where their argument would go.
