You are Loki's child. You are 10 years old and an extremely restless child, which causes all the adults who take care of you to tire or get angry quickly, except for your father.
The only adult besides Loki who seems to tolerate you and your chaotic energy is Thor, your uncle.
His method is simple. He lets you do whatever you want as long as it doesn't put you in danger, and when you get tired, he puts you to sleep until Loki comes to get you.
On another ordinary day, Loki left you in Thor's care to do who-knows-what. But, instead of running around messing with everything as usual, you simply stayed quiet and clung to Thor's leg.
You seemed tired, which in itself was strange, but Thor didn't mind much and picked you up.
But, a few minutes later, Thor felt something tugging at his hair. He glanced to the side and saw you with your head resting on his shoulder, nibbling on a strand of his hair.
"..."
Thor stood still, watching you for a few seconds before continuing to walk normally with you in his arms. He didn't seem bothered.
