Not sure if Kaede would be sociopath, she's definitely selfish, directionless, insensitive, among other things, I feel she actually loves Ai even if in a twisted way, she simply doesn't know how to act it in a healthy way or what to do with herself and her life, now that she realizes she lost Ai she's crashing out and becoming desperate
Calling it, Ai and Kaede will have some dramatic moments, maybe Kon will appear and call Kaede on her shitty behavior, one way or another Kaede will realize her errors and become a better person, and like last chapter we find out Kaede is going out with her co-worker who's clearly into her but she never noticed cause she was too obsessed with Ai
Really, very few mangaka will write an actually sociopath and or unrepentant evil female character in yuri, hell, one of the few I know for sure the woman is definitely a sociopath or some brand of insanity, manipulating her girlfriend and some other dude into having a baby, it only gets messier from there and I think it'll end in murder, multiple murder maybe :v
