Kokomi Teruhashi is on a secret mission to get the seemingly average boy, Kusuo Saiki, to gasp at her beauty, but is that really her goal? There's no way she's in love with him! The most perfect human being can't get with someone so...average. His looks, grades, personality, everything, is just average! Meanwhile, Kusuo Saiki tries his best to avoid her, but even his unworldly powers are weak to his own fate. As much as he tries to avoid her, she'll just keep finding him one way or another without even searching for him.
