Chiri is an office lady who is about to enter her 30s. One of her places of solace is when she is drinking with her beautiful neighbour, Kagami. Chiri first became acquainted with Kagami when she helped Kagami out after the latter had lost her keys.

One day, when Chiri was about to leave the bar where Kagami works, she saw Kagami speaking to a man who seems to be Kagami's boyfriend.

Even though she knows that Kagami is a woman, she is struck with a gloomy feeling that feels close to jealousy. Ever since then, she starts to feel conscious of Kagami...

This is a neighbourhood love story between a mysterious beauty and a dull OL.
