From Tokyopop:

A rude girl and an effeminate boy switch bodies and find that it might be a better fit for both of them in this crazy comedy:

Nanako Momoi is the belle of high school... as long as she stays quiet. Once she shows her true self, guys' dreams are shattered for she is a true tomboy. Akira Uehara has the looks and brains, but, unfortunately, his personality is so dull it overcasts a shadow, and nobody notices him.

One day, Nanako's grandfather comes up with a crazy invention, and Nanako and Akira trade bodies! She's in his body, and he's in hers!

Hana Suzuki loves only two things in life: eating and sleeping. So when handsome senior Izumi Oda asks Hana–his major crush–to join the school hockey club, persuading her proves to be a difficult task. True, the Grand Hockey Club is full of boys–and all the boys are super-cute–but given a choice, Hana prefers a sizzling steak to a hot date.

Then Izumi mentions the field trips to fancy resorts. Now Hana can’t wait for the first away game, with its promise of delicious food and luxurious linens. Of course there’s also the getting up early, working hard, and playing well with others. How will Hana survive?

Homare is a lovely first year high school student who has been sold off to the Ichinokura family as payment for her parents' debt. Although there are only guys in the Ichinokura family, they are all clean and kind, and Homare works hard as a pretty maid, including washing their underwear and their backs!

A smart, athletic, kind bishonen attending rich kids' high school, Taro Yamada seems perfect... except that he's actually dirt poor, living in a shack with 6 younger siblings and a mother with no sense of money and a perpetually absent artist of a father. Taro's main worry is putting bread on the table. He relies on bento (lunch boxes) that girls in love give him, works multiple jobs, and even has a "pet" dog for desperate times... Every day is a lesson in survival for the Yamadas.
