Even with the human way of birthing the author can realistically avoid the pregnant belly to show by simply just having the babies be born in snake form. Daddy snake was originally tiny in snake form too before molting, so it's easily possible for the snake forms of the twins to be super tiny when they're born
For S2, I'm thinking that Taesun's belly wouldn't bulge that much bcs the baby snakes will likely be born in egg form since they are reptiles after all. Google says snake eggs are a maximum of 5 inches in size. And two eggs in the same batch/litter is not that much. Unless the author doesn't go the oviposition route and prefers the human way of birthing, idk anymore. Also, didn't the sunbae and Geumryang meet yet? I wonder how Taesun will introduce Geumryang to him the moment they meet.
