a few chapters back, kon wanted to have matching necklaces but she was insecure about asking ai to stop using the blue garnet, now kon is more assertive to what she wants, she was pretty firm about moving out, and even about asking ai to delete kaede's phone number, she was confident ai would do it, but ai refused. that was pretty realistic. ai is trying, really trying to move on, she only started it for kon's sake, let's be real, kon begged ai to date her, kon knew what she was getting into. ai is in her right not wanting to delet kaede's contact.
