It's stated directly in the story that the chance for romance is 0. She has no romantic interest in him at all and he literally can't have kids unless that swordsman from the beginning dies which will literally take years both in the story and irl. Plus the last thing on his mind would be romance since he's trying to get stronger.
He could bare a children but there bloodline must be not be ranking among nobles
And there it was a female lead?? Is it way too early?? Haist
