The main character, Tokisaka Iori, is an inconspicuous high schooler, but secretly he is a well-known professional illustrator.

A mistake in a delivery leads him to be discovered by a beautiful silver-haired girl, Minase Asumi, who lives next door.

Asumi is an honor student who is known as a “saint” at school, he thought she was living in a different world from the one in which he was living, but one word from her changes everything.

“Tokisaka-san, you are my “Mama”, aren’t you?”

Surprisingly, Asumi is the person behind the popular VTuber “Kanadome Hyoka,” for which Iori was in charge of the character design.

“I’ll help with anything, even household chores, for Sensei’s illustrations.”

“Oh no, the viewers will find out everything! Cut off the stream!”

“I was only able to do my best because of you, Iori-kun.”

After learning each other’s identity, they eat dinner together, stream together on good terms, and help each other with household chores……..

In this way, their relationship, which they thought would never cross paths, gradually becomes entwined.

A sweet next-door neighbor romantic comedy between a heavenly illustrator and a super popular streamer――――is about to start!
