Spoiler!
Apparently, halfway through Jiwook gets groomed into being a dog. And it just gets worse and worse. Humiliation after humiliation. And Jiwook getting fuc*** by a dog is true. That's at the last chapter. And Juhyeon ends up enjoying it.
Apparently Juhyeon bought it for Jiwook and found out Jiwook is using the dog for… rim**** i think? And then that's when the fuc**** by a dog idea comes from. Then… End. It's a no romance trope.
