There is a bump. We don't have all the chapters here.
What chapters are missing? Other than the side stories
Blood Link have a baby bump
It goes up to 58. Zenmanga has them all but to be honest, I felt a bit sketch to get there (Google is easy to find.) I really wanted to know the ending and I tried other sites too but at some point, they either didn't have them all or the images remained broken and wouldn't load.
Since season 2 ended i assumed the chapters after chapter 45 and the artist afterword would be the side stories. Will be waiting for them to upload here hopefully soon :(
This turned out so much more wholesome and fluffy than I expected! I just wished there was a visible baby bump. Most BL stories with mpreg always have flat stomaches and or six packs lol
