Mpreg & omegaverse

It's not omegaverse. But they had son with the help of technology. The story time pretty random at first. N it's not vampire. Since the story pretty short, it's tough like how they meet. They truly had alot of job in their life. Like be office worker, bodyguard, someone from soldier or police thing etc. N it makes they kinda scared with bad thing may happened. That's why there's bodyguard in their corner. But it's okay, the story telling more about their cuteness.It's free in webtoon.
