Fujiwara Yuji lived a life without tweeting.
When I was in ○○, I was criticized for vases that were not even broken, and I was fired from work due to a mistake by a colleague.
At the convenience store where she works part-time, Takamiya, a younger girl, blames for the mistakes she made by someone else.
When I got home with a depressed mood, a strange girl greeted me.
In front of Yuji, who is confused, the girl reveals her true identity.
It was a mucus life form that I had lived with for three months.
A creature that can speak people's words and change their appearance has a crush on Yuji.
Yuji is cold to the kindness of mucus living beings.
In order to attract Yuji's attention, the mucus lifeform transforms into Takamiya, a colleague at his part-time job, and seduces her.
