My SunYang (Sunday x Welt Yang) headcanons (because I'm in deep now my fellow rare pair shippers)
-when they are apart they are fairly quiet people, but the moment they are in a room together, they don't stop yapping about philosophy, morals, and loss
-Welt will start talking about his home world and Sunday just listens so intently that he doesn't realize he's staring
-Welt loves animation and Sunday likes classical music; they do not stop talking about art
-they'll seek each other out for silent company
-Welt will ask Sunday a lot of questions regarding halovians, and Sunday will start asking about Welt's powers
-Sunday is the first between them to initiate any touch. Welt is so comfortable with Sunday he doesn't notice until Sunday dozes off with his head on his shoulder
-Welt is the one that successfully encourages Sunday to visit the world's they stop at
-Welt is first to realize their feelings for each other but leaves it up to Sunday to initiate anything
-Sunday is the only one allowed in Welt's room on a regular basis
-Sunday is older than Welt
-Sunday is one of the few that pieces together Welt's actual competence in most things regardless of his feigned ignorance
-they borrow each other's scarves sometimes
