To fall in love with a monster

Satori Tendou is a middle blocker in Shiratorizawa high school. People in his school find his appearance and behaviour scary so they avoid him all the time. They call him "Monster" and are really scared of him. Tendou got used to it and lives his life. He is preety cheerful though. He likes to spend time with his one and only friend Katsumi. She is the one who accepts him and his weird appearance. He plays volleyball and enjoys it pretty much. Then suddenly one day a new boy joins his school, and volleyball team. He is slightly taller that Satori and had this blank expression on his face all the time. He drags Satori's attention because of his unusual persnality. But unfortunately the new boy is really closed when it comes to talking to people. But Tendou won't easily give up. He wants to get to know this boy better. He wants to be his friend. Or....maybe more?
