Anime: Blue-Eyes Baby Dragon, picked up by the Knight King

Option 1: Become King
[Option 2: Become the male protagonist of a light novel]

The opportunity to be a human is there in every life... but the opportunity to become a Blue-Eyes White Dragon may only come once in this lifetime!

"Ouch——"
"Okay, that's cute."
“Can I keep it?”
