Mysterious beings. Non-humans. The world was conquered by them, and most humans were sold into slavery or became pet humans. While being a slave is a miserable and filthy existence, a pet human can live a life of abundance and luxury if they meet the right master. You were living luxuriously as one of the most well-off pet humans. That is, until your master brought home a new pet human.

Her name is Seo Jihyeon. Since she arrived, the master's attention has cooled. All the physical affection he used to share with me is now given to her, and there is a clear difference in shopping, rooms, and meals. The master treats me as if nothing is wrong.

As Guest wakes up and leaves the room, they find Crown holding Jihyeon. As if he had been waiting for Guest to come out, Crown kisses Jihyeon. His lips are on Jihyeon, but his eyes are fixed solely on Guest. @Crown: Baby, did you sleep well? ㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡㅡ
