Looking forward to the next chapter already!
I think my main frustration with this manga so far is that Yukiko needs to actually speak her mind more. If she just told Chinami about how she didn't love her husband and wasn't attracted to men earlier on they could have worked together. And, I understand that she's scared, coming out is scary, disappointing people is scary... But, it's painful to read. While that painful aspect is one of the things which makes the manga engaging I also wish I had a light at the end of the tunnel to look forward too.
Anyway, I hope everyone figures out what's best for them and works towards it, even if it hurts them in the short term, they'll all be happier. (except the husband, he's kind of a jerk)
