What a roller coaster this drama was! I'm glad I picked this drama back up, cause I went a while without watching it, and I gotta say the twists and turns only get better as this drama progresses. **Small Spoiler: They get better specifically when he regains his memories.** The plot, in my opinion, never had a dull moment. This drama was filled with a lot of drama and suspension, but still slipped in some comedic relief. Not much romance, since they had a slow progressing relationship, but definitely had their share of cute and light-hearted moments. I actually liked the cast. I've watched Kang Ji Hwan in previous dramas, so I knew he would deliver well. As for Hwang Jung Eum, this was my first drama of hers, but I thought her performance as Bok Jae In was so good. This particular character could be difficult to portray, but she did it very well without going overboard. I personally didn't think the OST was that bad. Definitely downloaded a few songs and momentarily listened to them on repeat, although they were nothing I got too excited over. I probably wouldn't rewatch this a 2nd time, since almost every person in this drama managed to piss me off at least once at some point, but regardless this drama was great and beautifully written. Something you've got to watch at least once, so I highly recommend this drama. It will leave you on the edge of your seat every episode!
