Rika has been working for an advertisement agency for 5 years, but she begins to suffer from mild depression after her sudden transfer to a subsidiary company. Frustrated about herself, and fell into a bad spiral, Rika finds herself in a position where her work and personal life are going nowhere.

Then one day, her pet cat, Haru, surprises Rika, by starting to talk to her. In fact, the spirit of a veteran psychotherapist who had been in a car accident transferred to the cat Haru and began to unravel Rika's emotional wanderings. Following Haru's advice, Rika begins to objectively look at her own behavior and thinking habits, to identify the factors that lead to her inner conflicts, and to start devising ways to avoid falling into the pitfalls of her mind.

Rika eventually overcame her conflict and learned to obtain a stable mental balance.
