Wow, so cool!

In the Korean comments

One comment points to the ending, reading in translation, “The scene where Lee Know chases Jeongin at the end is so cute.” Another calls the pair a “cat-and-fox duo,” offering a character shorthand to watch for.

깨물어주고 싶네 (kkaemureojugo sipne, “I want to bite you”) is literal biting language, but here it is a casual, affectionately exaggerated way of saying Lee Know is irresistibly cute—not a threat.
