I'm stil watching ep 19 and 20, but I come by to this thread. The hospital scene really funny, the bromance maybe will win MBC drama awards this year . I guess the women with red shoes will caught by KIS.
I think ahjumma from KIS is not the assasin. I have feeling that Seunggi mother is the assasin. We just hear her voice when yelling to her husband because watching TV about jet.
