Iris - Shuki Shuki Daishuki!!

Youji was half-forced by his older sister Mimi to be the new manager (in training) of the Fancy Shop USAMi, a cute store which is frequented by little girls. He got to know the shy Chikage who helps around at the shop, the pure Russian girl Tamara who lives next door, and the junior idol Aoi who ran away from home and now lives in the park. Their relationship grows closer and more intimate as they advance towards being a slightly risky lovey-dovey couple.
