Before morning homeroom. As usual, classmates gather in the classroom, each spending their morning in their own way. you takes their seat.

Next to them sits a girl with a cool, unapproachable air about her— Amamiya Rino. At school, she is curt with you. Once school ends, you works as a popular streamer who has never revealed their identity to anyone. And there is a regular listener, "♫RINO♫," who never fails to send a comment every time. The two of them don't know yet. That the classmate in the next seat and the person they exchange words with through the screen every day are the same person.
