Nothing in this world is perfect. However, some things are nearly perfect, and While You Were Sleeping is one of them. From a great storyline and plot to a great cast and amazing characters along with one of the best OSTs ever, While You Were Sleeping is a must-watch.

Story:
The story of this drama revolves around the special ability of a group of friends to be able to see into the future through their dreams. Throughout this drama, this group of friends and the people around get to see the ways their dreams affect the world of law, their love lives, and their day-to-day lives as well.

These characters realize that knowing the future, seeing it in their dreams, doesn't mean that it can't be changed. They face decisions at every stop, just like we do, except for them their decisions carry much more weight and can deal heavy consequences, good and bad.

All these key components are intricately woven together to create a plot that is not only interesting but also logical. The plot also shows how much each decision, no matter how small, affects everyone and everything around them. All this works together to create one of the best plots in kdrama history.

Acting/Cast (Spoilers Below!!!):
The characters and the cast that played them were spectacular. Unlike many kdramas where the characters are unlogical and do things for no apparent reason, the characters in WYWS make their decisions logically.

Yoon Moon Sun (Hong Joo's mom) has only one condition when she makes her decisions, her daughter, and that makes sense. She is a mother devoted to making her daughter happy especially after all the hard things Hong Joo is going through. All she strives for is to keep her daughter happy and safe. Her decisions and actions portray that mindset perfectly.

Lee Yoo Beom is the main antagonist of WYWS. He is driven by his greed for power to the point that he does many things morally wrong, and he knows it. Throughout the drama he is wracked with guilt and tries to make excuses for himself, driving himself deeper and deeper into the hole he has dug until he goes as far to murder someone.

Han Woo Tak is a fan-favorite. Loyal, kind, and even through many hardships maintains outstanding morals while always thinking of others first. Even though his unrequited love for Hong Joo was never returned with even a glance. Woo Tak valued his friendships with Jae Chan and Hong Joo so much more that instead of being jealous of Jae Chan and trying to hurt him, Woo Tak helped their relationship to move forward. Through Woo Tak, I saw what a real friend was. Someone who can sacrifice everything, even his love, for his friends.

Jung Jae Chan is far from your perfect protagonist. Instead, he is full of resentment, hate, and regret from his past. He struggles to keep his morals intact as he faces hard decision after hard decision in the world of law. However, Jae Chan is also a kind person and a great friend. Although he is aware that Woo Tak likes Hong Joo, he doesn't attack him or try to break their relationship apart. Instead he hides the fact that he knows it and shows the amount of trust and faith he puts in his friends.

Finally, Nam Hong Joo is a quirky girl, to say the least. She is always smiling and laughing, hiding the insecurites and fears she has. Hong Joo showed just how much fear can control a life. From her short hair to quitting her job, she lives in fear all the while trying to hide it. However, as the story progresses, she retakes control over he life, returning to her job, actively trying to change the futures she sees in her dreams, and facing her fears.

Music:
The OST of While You Were Sleeping perfectly fit the drama and also produced some amazing songs, including "It's You" by Henry (My favorite song), along with great songs: "When Night Falls" by Eddy Kim, "You Belong to My World" by Roy Kim, and "I Love You Boy" by Suzy and many more. Overall, one of my favorite OSTs ever.

Rewatch Value:
I don't really ever rewatch dramas, but if I were to choose one drama to rewatch While You Were Sleeping would be one of my top choices. Even though watching it a second time might reduce the thrill, it would allow me to catch some smaller details I missed the first time around.

Overall:
My favorite drama I have watched thus far. An amazing plot, logical and beautiful characters, and a magical OST makes While You Were Sleeping a must-watch drama.
