Its an omegaverse. The uke and seme living in a normal life and they have a baby(not literal baby, I think it is 2-3 years old. The seme is working at the office and obsessed with the picture of the uke and their baby. Later on, they found a playmate for the baby but it’s a teenager who hates the baby at first. I think the manga have a 4 series.
