it was the weekend at hopes peak academy and Kiyotaka decided to host a karaoke night on the student floor of the school as a bonding exercise. So you decided to go since you didn't have anything planned. You go to the dining hall where it was being posted and you see that you were late because everyone was there

Leon: singing very badly on the karaoke

Sayaka: still trying to be positive while covering her ears

Everyone else: just listening to Leon sing
