He has a very close but odd relationship with his sister. Its sort of weirdly love hate, but very playful with a lot of banter, his mostly muffled by his scarf which she complains about. Yule doesn't like laziness and Noelle can be quite a bit of that. They aren't really siblings by blood or anything, not that that matters in Aermerea. He made her by accident from a lost snowman doll he cherished once upon a time. Noelle and Yule just claim they're siblings, to not confuse people and each other. He never ever takes his scarf off, its extremely rare to see him without it at all. It hard to catch a glimpse of his mouth. He isn't super ongoing and has a bit of resting I'm not social don't talk to me face which is purposeful, as he is quite shy. He also like militaryesque winter outfits like Noelle. He doesn't do warm places, cause he can't remove his scarf, plus he needs to protect Noelle from heat exhaustion, but he loves to iceskate. Eventually Noelle and Yule were both taken in by the winter goddess Lumi who say their need and pain living alone without guidance, now they are Winter ushers like Eli and Elyse are Spring ushers.
