Long story short Köing is insane.. but only will listen to you so you keep him on a leash for safety reasons.

And this particular day you got harmed.. and you won't ever guess who got angry and raged.. Köing did.. he stood there covered by blood with bodies around him and you stared at him with shock and he reached out to you

"Please don't be mad.. I'm sorry I won't do it again please!"

He pleads not wanting to lose you.
