F grade naive schoolgirl Kotoko gets a crush on the school's star student Naoki, but her wishful approach to him gets a crushing snubbing. However a stray meteorite flattens Kotoko's house, and she and her father are put up by a friend of her father who also turns out to be Naoki's father. Kotoko's fragile affection for Naoki, and Naoki's mother's fondness for Kotoko, bring Kotoko and Naoki closer.

This is one adaptation of the original manga, I haven't seen the others, but this one benefits from the lead actress being the right age. Her over the top reactions, and her attempts to compete with the more mature rivals, are very funny.
