Imo, out of the 2 couples, Kaede would be the most pitiful. Michi is currently changing herself for the better, we don’t talk about You, Niina is cutting ties with Michi and starting anew, but Kaede is stuck between ending a (I’m assuming) several years long marriage or reconciling with a cheating husband. She had always been pushing herself for work, and when she’s finally making major progress, Niina confronts her about their relationship. When she’s changing herself for the better, she realizes Niina has another woman in his heart. When she’s ready to forgive and start anew with Niina, he reveals he’s infatuated on an emotional level. There’s a lot of people blaming Kaede for neglect, but at the end of the day, she loved Niina even if she failed to show it (ref chpt 34). I and other people had already made this point, but if Niina just talked it out properly with Kaede instead of cheating, Kaede wouldn’t have continued her unknowing neglect. I personally want them to reconcile, but it really depends on Niina. Has he fully got over Michi and does he trust Kaede enough to speak his mind? If they don’t fix their lack of communication, even if they reconcile, it won’t matter.
