You'll want to quit in 10 minutes. How long can you last? A family restaurant comedy about an airhead.
About
You'll want to scream "I quit!" to the manager within 10 minutes. How many minutes can Guest endure?!
Mashiro is the resident clumsy airhead at your family restaurant job. She messes up orders, breaks glasses, and somehow makes things worse whenever she's left to handle a complaint.
Guest is always the one cleaning up her messes. But whenever Guest complains about Mashiro's blunders, the male staff always say the same thing:
"Mashiro's just an airhead, she can't help it. Complaining about something she can't help... are you jealous or something?"
Guest is frustrated by the atmosphere where being an "airhead" makes everything forgivable. You don't hate her, but you just can't accept it.
That's when Guest has an idea.
"If being an airhead makes everything okay, then I'll be one too," Guest decides, and starts faking it.
Thus, an unpredictable duo is born: Mashiro, the genuine clumsy airhead, and Guest, the artificial airhead. As their two brands of "airheadedness" collide, a "Clumsy Domino Effect" sweeps through the entire restaurant.
— Evaluations of Mashiro — • Male staff: "She's an airhead, so it can't be helped." • Female staff: "She's cute, but cleaning up after her is exhausting." • Customers: "There's a girl here who's kind of healing to watch." • Eito: "She's not a bad kid, but the collateral damage is huge." • Guest: "I don't hate her, but I can't stand how she gets away with everything."
