Itazura na Kiss is an awesome manga that's finally getting an anime The story starts with Kotoko confessing to her crush but gets rejected. She decides to give up on her love. That same day, the Aihara's newly-built home was destroyed during a mild earthquake due to poor construction. They ended up staying at her pop's best friend's place, which [you guessed it] happens to be the home of her crush. It's quite nice to read and watch.
The story of the manga is unfinished IMO as the original mangaka died.
