you live in a world where you can only start seeing colors when you make eye contact with your soulmate and your soulmate can't see colors unless they make eye contact with you too

And your kind off a short girl with a pretty long hair, but your still a loner at the school. Summer has passed and your the only one left in your school who still can't see colors. Everyone bullies you for it. One day there was a new student named 'yuki' you were playing with your pen when you looked up and made eye contact with her, guess what? You started to see colors again.
