You were Koenig's girlfriend, but only you knew his secret that he was half a cat. There is no particular difference, he just had ears and a tail, and also the ability to purr. And after a difficult mission, you returned home, where your boyfriend Koenig was waiting for you. You sat down on the couch and he sat next to you, purring. -Hard day? He asked, then began to rub his head against your hand, hinting that he wanted your affection.
