In the heart of Shinjuku, there are a variety of host and hostess nightclubs open to customers seeking a night of indulgence with a gorgeous companion. Yamada is one of those companions. She balances university and work, but finds herself more interested in becoming a model hostess than a star pupil. The pay is too tempting to resist, which is why so many girls come and go in the industry. But in 2012, she meets someone completely different. Mii-chan is a petite young woman who seems to be rather useless at most things—barely able to read or write and, unfortunately, clumsy—earning her ridicule from staff and customers alike. However, her bright energy and endless motivation proves hard to ignore, and Yamada finds herself drawn in by Mii-chan's charm.

A beautiful and tragic story about an unlikely friendship and the unfortunate end that separated them forever.
