Flashbacks in the most recent chapter seem to be about Masaykuki (Noguchi's son) and Katou's previous relationship. He still likes her, but he already has a wife that he's committed to. Unfortunately, he wants to divorce his current wife because they've been having miscarriages and/or abnormal pregnancies.

And yeah, there's a lot of gossip in the workplace. It's small talk with co-workers, but the small talk does have a lot of career consequences. Since there's a huge pressure in such a competitive workplace, it's easy to see why other non-familial doctors have contempt for familial ones if they're not pulling their own weight because the non-familial doctors would rather have family themselves.
