The entire plot is a three-way romantic misfire where nobody wants the person who wants them. A-Ko's working fast-food shifts to impress a guy who's actually into C-Ko, while B-Ko's scheming to separate them both, and the whole thing plays like a slapstick farce that knows exactly how absurd it is. It's 1988 OVA energy: colorful, chaotic, moving at cartoon speed, where the joke is that everyone involved is chasing the wrong person at the wrong time.
A-Ko spends her school break fixating on romance, sparking a blowout argument with C-Ko that sends the younger girl running into traffic. When a mysterious motorcyclist named Kei saves C-Ko from disaster, A-Ko becomes instantly smitten. She takes up a part-time gig at a fast-food joint to scrape together cash for the perfect party dress, convinced that looking sharp will win Kei's heart. The catch: B-Ko also has designs on Kei and isn't about to let A-Ko have him without a fight. What neither of them realizes is that Kei's attention has already been claimed. C-Ko holds his gaze completely, leaving A-Ko and B-Ko to scheme and compete in total obliviousness. This third installment leans hard into romantic comedy chaos, blending the franchise's signature slapstick energy with genuine character stakes. The tone stays light and fun, but there's real tension in watching three girls operate on completely different pages about the same guy. Perfect for anyone who enjoys love-triangle nonsense played for genuine laughs and unexpected heart.
