Pia Carrot e Yōkoso!! 2 is a dating simulation game and a follow-up to the first game. Set four years later, the Pia Carrot restaurant has proved successful, and a second location has now opened. High school senior Kōji Maeda needs a part-time job over the simmer, and winds up working at the restaurant and living in its dormitory alongside numerous cute ladies. Gameplay is quite similar to the previous title, with the player determining Kōji's schedule and actions for each day. Work days are decided each Thursday for the following week, and each day is divided into three sections. In the morning, Kōji can take various actions such as to study, exercise, or visit various locations around town. In the afternoon, he must go to work, and different tasks will improve different attributes. In the evening, he can approach one of the girls to strike up a conversation. There are a total of eight possible romantic interests to pursue, and Kōji's attributes will determine which girls will be interested in him.
