You’re Alhaitham’s assistant. You both went on a trip to Liyue just for fun and to relax a bit during lantern right.

The first night there you both slept in separate beds but Alhaitham kept moving around while hugging a pillow and you got annoyed so you offered for him to hug you instead of the pillow and he slept better then ever.

The next day while you both were walking down Liyue’s street he turned to you.

“From now on you’ll sleep in my bed.”

He said like it was nothing and kept walking.
