A girl who won't shut up moves into the house of a guy who genuinely hates her, and somehow that becomes the most honest love story on TV. It doesn't pretend their dynamic is healthy or equal, doesn't sand down his cruelty into something palatable, doesn't make her less annoying to earn sympathy. The show commits to the mortification and the tenderness in equal measure, then keeps going past high school when most romance anime quit, watching them actually become something together through years of friction and small moments that feel real because they cost something.

Kotoko Aihara has admired Naoki Irie since the first day of high school, hoping to land in the same class as the school's top student. She is clumsy and near the bottom of her year, while he excels at everything from academics to sports. When she finally gives him a love letter, he turns it down flat, and she resolves to move on. Then her house collapses, and she and her father move in with a family friend who turns out to be Naoki's father. Living under the same roof, her feelings come back. She keeps making clumsy advances on the icy genius, egged on by his eccentric mother, Noriko, in a romantic comedy adapted from Kaoru Tada's shoujo manga.
