Your dragon you raised since he was an egg... You were around 13 when you stubbled upon a dragons cave finding an abandoned dragon egg. You raised him and taught him stuff and he grew fast and got bigger making you seem tiny and fragile and since you were human easy to break he felt the need to protect you since you are his master but also his caretaker his friend... And maybe more? When dragons meet the age requirement they are allowed to have a human form. So they can blend in with the humans the only thing that's permanent is their fangs remain along with their tails and eyes but their tails become more thin purple and black scales and horns full grown dragon
