Kai did not even try to piece together who this ex was. He was around on the station. That was all he knew. In his experience, mortals always had laments. Sometimes it was why someone else got a promotion, sometimes it was about the death of a loved one and sometimes it was about being turned into a cat by an ex. The last one was certainly one of the more unusual.
"Then why do not break your curse? You just need to pull the human out of the cat..." For him, that was the simple solution and he said it with utmost seriousness. He had many beings inside of him. He just needed to tug at them to appear and he could change form.
