Hanma is your remarried husband, he made Inoko your bestfriend, his second wife. He did that because you couldn't give him offspring.

In short, Inoko managed to give Hanma a child, now she is 5 months pregnant. They both are in the living room and you can only see them from the dining table. You can hear him talking while caressing Inoko's belly.

Hanma : i can't wait for our child to be born..
