I started watching this drama thinking that it would be another romantic comedy drama.Cast: Ji Chang Wook and Nam Ji Hyun.Although I've seen Ji Chang Wook before (and he is an amazing actor),this was my first time watching Nam Ji Hyun (Eun Bong Hee),Choi Tae Joon(Ji Eun Hyuk).The supporting leads too have acted well. I started with the first episode and it was good.I thought of continuing further (ofcourse because of Ji Chang Wook).And then....last few minutes of episode 2 and it turns out that this is a thriller-suspense drama! (haha I hadn't seen the teaser or the trailer before selecting this drama )Also,tbh, I love mystery-suspense-thriller dramas and the fact that I wasn't expecting this one to be a thriller-suspense drama was even more awesome! That's when I decided that I just had to continue with this drama! Since Episode 3 till now,this drama is just awesome! The story is great! The actors have played their roles well .I like Ji Wook & Eun-Hyuk bromance (lol) and ofcourse the chemistry between the main leads (Ji Wook and Eun Bong Hee.) :D So I'd like others to watch this drama(although it's a suspense drama,the more you wait,the more exciting it is to watch the new episode.Btw there are 2 episodes every week so YAY! although they are 30 mins each;so that would be an hour altogether). Overall:9.5/10
