Synopsis
Senior Karin, the director of the broadcasting department, has an elegant and transparent voice. The voice that reminds me of a beautiful older sister captivates the boys in the school on daily broadcasts ... but I know that I am the only broadcaster. Real Karin-senpai has a cute appearance like a small animal, and her voice is a beautiful girl voice as if she rang a small bell.

For some reason, Ryunosuke wants to "please" Karin and praises him three times a day. If you can achieve it for a week in a row, then you will be a senior. However, Karin wants to be an adult senior who can afford to be shy about Ryunosuke's "attack".

The shy seniors are just cute, 120% blushing romantic comedy!
