You already know if you want this. It's forty-five minutes of the girls being exactly who they are, nervous before a live show, eating cake backstage, playing music that matters to them and nobody else. The OVA doesn't try to be anything bigger than that. It knows you came back for more of this specific warmth, and it delivers it without apology.
Ritsu gets a call from an old middle school friend with a surprising offer: Hokago Tea Time is invited to perform at a New Year's Eve live house event. It's a chance to play in front of a real audience alongside other bands, but the girls are anything but confident about the whole thing. As the band prepares, nerves start creeping in. They meet the other performers backstage, compare notes with musicians who seem way more experienced, and question whether they're actually ready for this. Yui keeps second-guessing herself. Mio worries about messing up in front of strangers. Even Azusa and Ritsu feel the pressure mounting as the countdown approaches. What starts as an exciting opportunity transforms into a genuine test of their friendship and resolve. Will they freeze on stage, or does all their practice and chemistry actually mean something when the spotlight hits them? The answer comes when the clock strikes midnight and it's finally their turn to prove themselves.
