If you don't know what SLS is, it is the infamous Second Lead Syndrome! It's definitely not a pleasant feeling to have, I can assure you. The good thing about this drama, is that

Let's delve in to the plot of the story. I really liked the way it was written because it is a trope we see less within the Joseon era and because it also had subtle mystery flavors behind it as well. Though I feel like some of the characters were unnecessary to the plot, they certainly did bring their fair share of comedic relief. In fact, this drama reminds me terribly of Mr. Queen in terms of humor.

Moving on to the cast, I love Hyeri, but I want to see her play different roles than the ones she typically does -- the "tomboy" characters. She's gorgeous as always and did a lovely job with portraying her character. Next, we have Yoo Seung Ho. Honestly, I didn't like his character at all. Other than the fact they were connected through childhood, his personality made no match for her-- hence why I got SLS. That being said, I believe that Byeon Woo Seok did an excellent job of portraying his love for Hyeri's character but also having a change of heart near the end. Kang Mina was one of the characters I unexpectedly fell in love with. She screams "main character," and I love that about her. Kudos to side characters and couples, Sim Heon and Woon Sim & Cheon Geum and Chun Gae, for their contributions to the story as well.

Overall, I would RECCOMEND you watch it.
