It's Koto Sanomiya's first day at a new school. In front of his new classmates, the boy introduces himself with a stoic face. He is looking for a girl who goes to this school. Her name is “Azami Yako,” the daughter of a corporate president, and the one he was "promised to marry" when they were young.

He can't wait to see her again… He still keeps a picture of her from junior high!

But when when he sees her current appearance, it turns out she… acts kinda strange, has a full head of shaggy hair, makes a mess when she eats, and talks a little too loudly. She has gone from a proper young lady to become a complete mess...?

A romantic comedy about a boy who wants to fall in love with a weird girl.
