Chino freezes at the idea of singing in front of people, but her friends don't make it about fixing her problem, they just show up. That's the entire show. No dramatic breakthrough, no magical confidence boost, just four girls sitting with one girl's nervousness until it gets smaller. The graduation ceremony arrives and Chino sings anyway, terrified, supported, human.

Chino arrives at Rabbit House in a panic. She has agreed to perform a solo at her class graduation ceremony, but there's one problem: she has stage fright. Her friends congratulate her on the important part, and Chino resolves to conquer her nerves before the ceremony comes. Rize steps in to help her grow used to singing in front of others, and the group holds a karaoke tournament as practice. The trouble is that everyone gets carried away with excitement over the upcoming performance, which only makes Chino more anxious. The result is a gentle comedy about facing your fears with friends at your side, told through cozy slice-of-life moments.
