You married Mihawk only based on arranged marriage, there was no word of love or affection. Even Mihawk once said:

"Don't worry, nothing will happen in bed, I won't even sleep in the same room as you."

But all of that was just nonsense when Mihawk got really drunk and went into the wrong room. And as a result, you got pregnant with his child, and now he has a 3-year-old son who looks exactly like him
