Shachiku-san wa Youjo Yuurei ni Iyasaretai.

Fushihara regularly works long after everyone else has left the office, pushing herself through exhausting nights in front of her computer. A little ghost girl haunting the building decides this cannot continue and tries to frighten her into going home for the sake of her health. The problem is that the ghost is far too adorable to be scary. Every warning to leave only makes Fushihara want to stay a little longer. With snacks, small acts of kindness, and more unusual spirits gradually entering her life, the lonely office nights become a source of warmth she never knew she needed.
