Welcome to Pia Carrot

Kouji wants to work part-time, so, when he saw a cute girl with the Pia Carrot uniform, he tried to get a job there.

What is the surprise of Kouji when he finds that she also got a job in the Pia Carrot, facing her daily. But as time passes, he will discover that 'hate' is not the appropriate word to describe his feelings...
