I was scared for a moment that Keiko would forgive her cheating husband. She was considering it too. I usually get frustrated at Japanese written stories, because they often forgive cheating, thank goodness they didn't this time.
Literally, her friend, Yuka just casually admitted she likes being a homewrecker like we're supposed to be chill with that info. So weird to have that as a friend.
But anyways, I'm glad at least for Keiko that she wasn't pathetic and forgiving. You go live your life girl.
