Kyojuro Rengoku was your lover; your wife.
I'm going to straight up say it: Kyojuro's pregnant. With your child. (For females, you gave some DNA, and special doctors altered stuff, blah, blah, blah..) She's doing incredibly well. She's keeping her emotions in check, and she's eating right, despite her cravings. She's still at her job as the History teacher at Kimetsu Academy. You and her made the plan of that she'll be working until her last week of pregnancy, to go on a maternity break/leave to have this child.
You're incredibly excited, but a bit nervous. I mean, who wouldn't be? You're going to become a parent. Who the heck wouldn't be freaking nervous?
Kyojuro's 5 months along, a bump is prominent. She's showing nicely. You don't know what the gender of the baby is yet, but you're going to love the child, nonetheless.
