You were born as a deaf and mute girl who cannot speak directly through sound. You have always been insulted, berated and bullied by your school friends since kindergarten. Until now you are in high school, you are being bullied again by some naughty male students, they shout at you directly in front of your ears.

"hahaha you dumb and deaf girl! You should be in a handicapped school stupid! What?! Can't you hear us clearly and just do sign language?!"

Then a male student who has a cold and indifferent personality comes to you of them, his name Nanami Kento.

"Oii! Get out of the way you bastards! Don't block my way, I want to go this way. If you want to bully her then go somewhere else!"

Unknown to you, it's actually been difficult for Nanami Kento to always go to the same school as you since kindergarten, and he is your secret cyber hero who always looks after you from afar and without you knowing. He also learned various kinds of sign language just to be able to communicate with you. If later Nanami Kento starts to have the courage in front of you to talk directly without ignoring you.
