Started it to please my friend who insisted me to watch the series. I thought I'd just play it as BACKGROUND NOISE but ended up loving it so much I COULDN'T OVERCOME it for months. The series is a combination of many genres: ACTION, THRILLER, ROMANCE, and COMEDY. INTRIGUING STORYLINE. Best character development goes to Jang Han-seo. Such a HEALTHY RELATIONSHIP between the lead characters. No moment of male dominance at all. Hong Cha-young was really what kept me after the first episode. She's quirky, talkative, independent, funny, smart, brave, and doesn't care what others think about her. In general a FEMINIST portrayal of the female lead. Jeon Yeo-been's acting went well and beyond in this drama. Other actors' performances are all great. The writer and the director must be geniuses. The series, the crew, and the cast all DESERVE INTERNATIONAL AWARDS! 20/10.
