Yeah, but he hid his pregnancy from Jinguuji....actually, Jinguuji doesn't remember Kairi from the baby-making time because Kairi asked him to forget him. As to why he actually does that, well...I don't want to spoil it for you (yeah, I read the entire raw, it's a oneshot manga), unless you want me to.

Ok, spoiling it it is, then. We have to go back to 5 years before this story, when Kairi was still working for the company as a student. Back then, he wasn't a marriage counsellor yet, just one of the attendants at a match-making event held by the company.
At such an event, Jinguuji attended as a VIP. He got drunk and was feeling sick. Kairi had been in the men's bathroom too, so when he saw Jinguuji, he offered to help bring him back to his room. When they touched it triggered Kairi's heat. Midway to his room, Kairi became extremely bothered, and Jinguuji also got into the mood. So when they reached his room, there was some pretty heate touching going on, but Jinguuji stopped.
He told Kairi to "run away", because once he started, he won't stop until he's claimed him. Kairi was hurting from his heat, so he spread himself and asked Jinguuji to take him. So baby-making happened.Jinguuji bit him, and then asked him to live with him.
Kairi thought that it was his heat that was making Jinguuji say all these things, so he felt really bad. He felt that he used Jinguuji(but later on from his view, he fell in love with Kairi at first sight too), so he just asked JInguuji to "please forget everything about me". Then he left while Jinguuji was stil asleep.
