Well duh have you actualy read the manhwa? Sure Jonggu was such an asshole but you can't change nor deny the fact that his master was such a toxic bitch as well, using his own dog as a filler for his lust and desires, completely ignoring his dog's feelings and hurting him.
But anyways ig the master is slowly realizing his true feelings for Jonggu, seeing him cry and desperate for his dog's arrival was so satisfying lmao the majority liked it. He deserved it, the dog got his heart torn now its his turn =0=)/
she got a whole 4d display(⊙…⊙ )
