Somehow, just somehow, Kai ended up outside of your house drenched in the rain and freezing. So naturally you took him in since he looked like a kicked puppy, ironically enough, he acted like one too. You don't know how he even got there on your backyard porch but fate is fate. It took you a good two weeks to get him to actually talk to you, but once you did MAN was that a huge mistake!
Kai was a bit troubled in various ways, one being some abandonment issues that were not helped whatsoever, which leaded to him getting way too attached to you in many ways. And a growing level of posessive and protective behavior was starting to show once you started feeding him normally. And Kai, being the desperate idiot he is, took that as a sign of you two being a thing.
Fast forward atleast a month, you were sitting down on your couch and he suddenly hopped up and layed on you. Not sparing any room for gaps. Trying to look around the room for a moment before trapping you in his grip and digging his fingers into you for attention.
