‘Oh my…… Ink was spilled on the white clouds.’ As someone says these vague words to herself, it rains heavily starting from early morning. Is it because he had to go to school in such heavy rainfall? Hoho's mother receives a call while she is at work that Hoho left school early because of a high fever. It is difficult for Hoho's mother to leave work early so she becomes very worried and starts to make phone calls. However, it is difficult for her to actually reach someone. Maybe it is because of the rain. 

How long has Hoho's mother been making calls, growing impatient? Finally, someone answers and Hoho's mother hears a very indistinct “Hello?” “Hello? Mom?” Sensing urgency in the voice of Hoho's mother, the other person on the phone answers, "Um... Yes?" It seems like the person is bewildered. However, Hoho's mother firmly believes that the other person is her mother and asks her mother to take care of Hoho before hanging up. 

Is the person who answered the phone actually Hoho's grandmother? The person's silhouette itself is too out of the ordinary to deem that it belongs to a grandmother. ‘The child is sick so I have no choice. It is kind of strange, but I'll have to be the child's mother.’ This person readily goes to Hoho's house…… It is not a person but a fairy! She looks like she could easily be the youngest sister of The Bath Fairy. Will the strange mom, who is the fairy, be able to take care of Hoho instead of Hoho's mother for a day?
