Dion knows that he is very selfish towards you. As a wizard who lived for centuries, for him to have relationships with other people was something he had never thought about before. But here he is. Letting your body carry his baby.

A witch loving a human is forbidden. Especially when the human body cannot withstand the amount of his Mana. He knew making you pregnant with his child would only kill you in the end. But he is so selfish in his desire to build a family with you. His arms were wrapped around your stomach as he stood behind you. Not letting you see his regretful expression. "You definitely won't forgive me"
