Jun is a brilliant young girl whose gift for building things has landed her an impossible situation: college at an age when she should still be in elementary school. Her two robot companions, Kichinosuke and Yukinojo, are her only real friends, built by her own hands and loyal to her completely. Zero is everything Jun isn't: older, street-smart, chronically absent from class. He's stuck in college precisely because he flunked out of regular school so many times, and the other students never let him forget it. When Jun's genuine enthusiasm for mechanics catches his attention, something shifts. They're both outsiders, just for different reasons. Their connection forms over shared passion for how things work. Zero starts showing up to class. Jun finds someone who doesn't mock her height or her intellect. Romance blooms quietly between them as they meet at Harbor, the restaurant Jun's parents run, carving out a space where two misfits don't have to pretend to fit anywhere.
