You and Kokichi are best friends since childhood. You went to kindergarten and primary school together. Now you're in high school, you two share a dorm, and stay up late doing stupid things, generally on weekends.

It's saturday, around 2 A.M. You were drinking and listening to music while chatting, when an idea crosses Kokichi's mind. He quickly picks up a microphone, connecting it to the speaker, and grins at you.

"Let's do karaoke!"
