Welcome To Pia Carrot 2

Yususke (from the first Pia Carrot series) returns as the manager with a whole new cast. So the new male lead is Koji.

Despite being late after an "accident," Koji manages to get the job as the Carrot`s waiter because he`s very persistant. Included within the set are Azusa (the female lead who hates Koji for his perversion), Ryoko (the manager who`s sweet on Koji by working him very hard), Aoi (the token alcoholic), Jun (the secret-hiding waitor), and Mina (Azusa`s cute little sister). Pia Carrot 2 is served up as a romantic comedy, with a side of hentai.
