I don't remember but does he know that kayden is the cat?
I don’t think he knows that kayden is a cat, but I’m not sure. He saw Kayden in action during the Crane Brothers fight and kayden told him to keep his mouth shut that he saw him. The others have not seen Kayden in his human form but wooin has, so it probably feels awkward to see him again..
Actually I forgot to add that wooin’s first encounter with him was when Kayden was beating up his foster father and was about to kill him. The times that he has seen Kayden have all not been very friendly so that’s why
wooin: profusely sweating
