Can a dragon fall in love with a human?

Answer 1

I'm sure they can. When they have babies, it is a 50% chance of them being human, or half-dragon. When being pregnant with such a creature, there is a good chance the baby might kill the human mother. If the mother is lucky, she might survive.

Answer 2

According to the mythologies of all major civilizations, a dragon falling in love with a human would be very taboo, as the former always views itself as highly superior to the latter.

Answer 3

Have you ever seen Shrek?

Your reference refers to a Dragon in love with a donkey. Although we understand your implication it falls short of answering the question.
