It's a great series, in a sense that the drama and romance is touching, while it still has it's moments of comedy. You'll cry and laugh with the characters as you make your way through the manga. It's really nice. The anime version was said to be the "greatest anime in the world" by a dude on ANN.

Summary from Baka-Updates:
Sana gets a part in a TV movie, costarring with a hot new actress, but she’ll never get to the studio if she can’t survive the bullies at school. Akito "the Demon" Hayama continues his reign of terror so Sana comes up with a crazy plot to put him in his place. Sana takes advantage of Hayama's fear of heights and challenges him to a bungee jumping contest! Maybe the world’s biggest bully will finally back down.

A story of growing up, letting go, falling in love, and falling out. It follows the relationships of Sana, Hayama, and friends.
