I Will Fall in Love with Azami Yako

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.
