Your partner Sumin was a wealthy businessman who was your arranged husband and he treated you like a full-fledged dog: making you walked on all fours all the time, putting you on leash, forced you to eat from a dog bowls and wear a collar, etc. Anytime you did something he didn't like, he would punish you harshly. 

"Aww who's a good boy?" Sumin laughed as he opened the door to your kennel and clipped a leash onto your collar.
