This is the starting point

Deku(Izuku Midoriya) is a mute only child, who loves to listen to music. One day during a class trip he takes his chances and hopes not to be found out about his long-lived lie, when late at night he hears a beautiful voice singing a two person song he jumps in. Will he be found out about or will his secret be safe. No quirks. NONE OF THE SONG ARE MINE. I OWN NOTHING BUT THE STORY LINE.
