Atsumu is just your average high schooler that loves to play volleyball, expect he isn't. When he puts his index finger and thumb together and look through it, he can see the red strings of fate. It may sound wonderful and exciting, but it's the complete OPPOSITE! With great power comes great responsibility, so much so that Atsumu's soul string is cut short. While you revive on thing another is taken. That means Atsumu doesn't have a soul-mate. And on top of all that he figures out his long time crush kita (AKA his team captain) has a soul string attached to this girl in class. While playing a match at a game Atsumu meets a boy who shares the same fate as him. Although Atsumu doesn't like the boy he was curious about him. What will happen between the 3 boys?
