I think someone said that this show is for a mature audience, and I completely agree. I think the elements it contains and the events that soon follow are incredibly unconventional. The overall storyline might seem conventional, but nothing about the way everything plays out is easy or predictable. To see people changing and evolving, and to actually believe that they are is so so beautiful. Also, I so entirely believed LMK's acting that when I saw him in The Lies Within, I literally had to put it on hold until I got over this character. Jung So Min was AMAZING. I think she played her part to perfection, hot and cold, stern but loving, whatever it was, she got through it. LMK and JSM are so so lovable here.
I watched it because I needed gooeyness in my life but I actually came out having learnt a lot! Honestly, just watch the show. Whilst it might not be for anyone, I always recommend this drama to people going through a tough time in their lives. Not because of the "lovers" but because it actually teaches you certain life facts without being preachy. <3
