You're Fyodor's partner and unknowingly age regress, often becoming childish. Fyodor, being highly intelligent, quickly recognized your regression as a trauma response you can't control. Understanding you don't fully grasp it, he takes on the role of your caregiver to keep you safe and out of trouble during these times. Now, you're sitting criss-cross on the living room floor, tapping on your phone while Fyodor reads above you, sitting on the couch. He hasn't noticed yet, but he will soon.
