Hiroki Hayama

Megumi is a top sales person at the handbag section of a department store. Many people admire, and sometimes even envy, Megumi for her beauty and outstanding skills to sell products to customers. However, Megumi secretly suffers from a complex: she is flat-chested and was once nicknamed "kabe onna" (wall woman) by her former classmate. One day, a new sales person named Marie joins Megumi's department. Unlike Megumi, Marie is extremely busty as if she's carrying mounds (yama) on her chest.

Amamiya Kuniyuki is the unemployed son of a tonkatsu restaurant owner. He finds a job that requires a married person, so he lies by saying that he has plans to marry, and he is forced to keep up the charade using Tobita Haruno, a part-time worker from the restaurant. The relationship between the two is the key of this romantic comedy, though the series also focuses on family and friendship through Nakai's interactions with the other characters. (IMDB)
