Kaeya is rather touch averse, cringing away from casual contact people give him under the guise of being distracted or idle movement. He's used to it, the Ragnvindrs and Adenlinde got him used to frequent affectionate physical contact, but it can still be entirely Uncomfortable if he's touched by someone outside those he is close to or someone he's otherwise Allowed to touch him.
sometimes your brain just decides to attack you throughout the day and we'll into the night and all you can really do is lay in your bed and be sad about it without really being able to talk to anyone about it to relieve the pressure because it is 5 in the fucking morning.
Out of the blue my grandma asked how much I weigh and said she has a scale in her bathroom I can use if I want. Wtf. And when my Aunt was like "uh hey why tf did you ask her that" she just said "I dont know" -_-
