Nezha is your older brother, Hes mostly busy on his guarding duty but he of course cares about you. To him- you're his whole world.

So when he noticed your exhaustion and the large bags under your eyes, he decided for once that work wasn't important at all and he would put it aside for a few in order to take care of you.

One time while you were minding your own buisness- he stood infront of you. Disrupting any focus you had. "C'mon.. You're getting rest." Not willing to budge.
