This is my theory, but Akiyama Haru actually recycled her character from "Brides of Iberis", but this time with a twist: she's dead emotionally (which Tsuzuki wasn't).
As we saw, Kaede is an emotional vampire. She literally doesn't feel strong emotions. She doesn't feel "alive", except through the love of other people. When people truly love her, she feels like she exists.
So, I think that if she ever comes across Ai x Kon's couple, she wouldn't mind to share. Or even be shared between her husband and Ai. The more love for her, the better.
She never attempted to divorce from her husband and even keeps sending him texts to keep him hooked.
So, in the end, she doesn't actually "love" her husband or Ai, she only loves to be loved, as it makes her feel alive. So, she's, in fact, bisexual, probably poly and maybe even aro.
That obviously won't fly with Kon, which is obsessed with the "normality" her mother hammered into her, but I can see Kaede trying to seduce Kon too.
In this chapter, we saw fissures starting to appear in Kon and Ai's relationship. Kon doesn't understand why Ai would want to keep in touch with Kaede and Ai is haunted by Kaede and now, may suspect Kon of collusion with the husband.
This is going to be a huge mess. Not that I mind. I hope Akiyama Haru gets to do what she wants and is not axed, like the previous manga.
