Kininaru Kurumi-san!

Synopsis

A plain, quiet guy named Fujimori admires a girl who's too beautiful, Kurumi. Because of his shy personality, he freezes up and can't speak when he gets attention, so he's never once talked to her and they shouldn't have any connection... or so he thought? A wild, emotionally intense beauty and a gloomy, oblivious boy—their clumsy, mismatched love comedy begins! (Source: Shueisha, translated)
