ギャルの自転車を直したら懐かれた

Kousei Kutsuzawa is a friendless, socially awkward boy whose one pleasure is tinkering with things until they work again. Walking home alone, he catches the most popular girl in his class before she topples off her bicycle, quietly repairs it, and turns to leave. She looks at him with shining eyes instead, and the flat, solitary stretch of his days starts turning into something like a romance.
