My mate is Lance?!

Lance was born colourblind...but in the weirdest way. He could only see red, blue, and purple. Countless doctors tried to figure out why but to no result, he was just born that way. Lance didn't let that stop him though, sure everthing was gray-ish to him but that didn't matter to Lance. Ever since lance was five years old his sister, Allura, took care of him. He doesn't remember his mother or father so he isn't to sad about it but still his parents did die rather strangly. Lance only wears blue because its one of the only colours he can see.

Keith has a single father named Shiro. His mother left when he was young but gave him a red bandana so he wears it everywhere. He has perfectly normally vision and has a pretty good life with his dad. He is very very very gay but not alot of people know it only him and his dad.

Lance and Keith go to the same highschool. Allura works at the school as an assistent teacher so Lance can't get away with anything. He often stares at Keith since they have all the same classes and he is always wearing red...

Keith: "Why are you always staring at me anyways?"

Lance: "Well...you always wear one of the only colours I can see..."
