@MoriumMirzakhani Hello! ☺️ To be honest, I haven't focused much on the concept of legacy because my main priority is the characters' relationship and their development. In the world I've built, anyone can be a spouse regardless of gender, so M-preg isn't a factor.
Even though Tian Xu Ning is the sole heir and the only one who can carry on the family name, I chose not to include M-preg. I wanted to explore the pressure of that responsibility within the existing biological rules of their world. Also, since I’m using the real names from Tianziyu, I was a bit worried about how M-preg might be received, I didn't want it to feel weirded out about it or for readers to be unhappy with that direction.
