I am not sure if words can do justice to a show like this. One can only begin to appreciate the mind of the writer who came up with the storyline in the first place. While many people compared this with the original Taiwanese counterpart, this is a story is beautifully portrayed and enacted with the actors.
Ahn Hyo Seop and especially, Jeon Yep Been are phenomenal actors to be able to multiple characters in the same scene. The ability to personify awkwardness of Kwon Minju and the charm of Han Jun Hee shown within the same person cannot be copied or taught. Not to mention the beautiful sound tracks which resonated with the storyline so well.
I am really in awe, and I think it is probably going to take me a little while to get over this. Hopefully people can watch this show and enjoy it (without comparing with anything else). That would a justice for the drama like this.
