I knew it! It's the head nurse! That's why she always meddle with them.. and I smell something fishy before.. I wonder what's her relation with MY if her mother really died ? but oh men, please, don't let Mun-yeong leaves Gang Tae now that she knew the truth.. ? Please Gang Tae, be with her.. take care of her.. now that the real enemy revealed herself.. we do not know what she'll do to her..
