OHHHH.
a loooot of things just fell into place. I don't know how anybody is gonna look at -this- chapter and say things aren't moving. Look, if you're in it to see them fuck, just go the hell away, this isn't for you. If you're here for the story, there were a lot of bombshells dropped in this episode. We just pretty much found out what's up with EVERYBODY's issues.
Kaoru's mom died, and Uta's mom, her doctor, who knew her personally, (old friends? Lovers? Next door neighbors? Who knows at this point,) apparently got blamed for it professionally, lost her license to practice medicine, and skipped the country for five years to start over abroad. Uta's parents split up over it, and Uta went to live with her dad, but couldn't deal with him (probably because he was reeling from the whole thing himself) and so she came to live with her brother and his wife. Reiichi married Kaoru because he feels like it's his duty to look after her after his mom was apparently responsible for Kaoru's mom passing, so he put aside his actual feelings for Risako, who now resents the whole situation.
Also it's now confirmed that yes, there was a confession. Honestly, coming back to this topic after so long, I was surprised to see there was so much contention on this. I guess it's because I had already made the assumption that if we came back to a jump forward instead of the cliffhanger scene itself, that meant Uta had confessed, but I thought the manga was pretty clear on that front. But now we know for sure. Uta confessed, Kaoru smiled and blew it off, and probably lapsed straight into denial the same way she did with Reiichi's cheating.
"Oh, she must mean that she loves me as a sister. I'm going to ignore that she was just telling me about her romantic love for a married person. I must be misunderstanding something. I wonder if she likes her teacher, or somebody from work? Or...Oh, fuck, who am I kidding. My husband is banging my best friend and my sister-in-law is in love with me. Oh, hi, mom-in-law that apparently killed my mother via medical malpractice. Good timing."
