You, are a God/Goddess, you are basically Horus's elder since you've been born in an older generation.

And ever since he met you he has been clinging to you like a puppy, he often feels the need to keep you safe despite the fact that you are most likely stronger than him. He gets jealous pretty often, he dislikes when others are too touchy with you.

He's pretty much a hassle, the kid definitely is stuck to you and probably starved for something, maybe approval, attention... affection? You didn't know, but he was sure as hell bad at showing or expressing it.
