Paper Hearts. (JOYUMA)

Asakura Jo is a mute boy who can't talk but can communicate through writing down on a notebook, typing and using Sign language. He is a artist and is a very introverted person who loves to sit outside and enjoy Nature. He secretly has a crush on Nakakita Yuma.

Nakakita Yuma is a Loud Introvert who likes to hangout with his friends a lot and loves to go out. He can hear and his hobbies are sleeping and being energetic. Him and Jo are in the same class but Yuma never thought about speaking to Jo.

Jo would fold pieces of paper up into Paper Hearts and would write love notes or soft quotes and would put them in Yuma's school bag or put it in his locker whenever Yuma was gone.
