The character design was nice, and the colors were pleasing to the eye. Although the contrast between the color palettes of the two love interests was super obvious, it looked great when they were together in the picture, like sun and moon, black cat and golden retriever. And in the center of it all, Jooin was... brown. The perfect color to be in the middle of the love triangle. Predictable, but functional. In short, the star is just for the drawing.
As for the story:
1- Jooin was an idiot until the last chapter. MAN, PLEASE LEARN TO MAKE DECISIONS WITH YOUR HEAD.
2- Yahwi, at least he adopted the blessed cat, but good god what a piece of asshole he was 90% of the manhwa and why????? WHAT WAS THE REASON?!?!?!
3- Cain, aka the dog man. OK, I get it, we've all wished for a man with golden retriever vibes, but ONLY THE VIBES, not a dog-man pseudo-hybrid with a strange love for his master from a past life(?). I think of this character and the only thing that comes to mind is the episode of Caso Cerrado with the man who says "Yo soy un gato, yo me siento como un gato".
4- The position of favorite character is contested by the dog-man's short brother and Yahwi's pot-bellied cat, probably because they weren't given more screen time to hate them.
