Their spin-off manga has already come out and is still ongoing, but it hasn't been translated yet, I've only seen a few photos on some social...
Given the dialogue they had in this manga, I thought that the driver/bodyguard was just a tough omega but actually they are both alphas, and Haruki is even the bottom, so I'm afraid there won't be any child...
Aw, no babies?
No, unfortunately there's no way they can have children because they are both alphas. What I think happened is that they just saw Aoi and Akane with their little girl, and so Haruki just seized the opportunity to make a love declaration to his guardian by saying those things... I think the author with that conversation just wanted to make us readers understand that they were the new couple for a new work!
I need a story on the Yakuza guys. Like, hello? They promised a baby!! So, SHOW US!!
