This drama was my absolute most favourite K drama. The storyline was just perfect, there was no cringy lines or scenes, the plot was neverendingly getting better leaving me hanging, and the acting of Lee jong suk and Bae Suzy was top notch. The duo definitely brought happiness and tears. The drama was very realistic and subtle as the drama left me wanting more as it didn't bore or tire me as my predictions on what might happen next were destroyed entirely. This drama made me cry almost with the superb ost (when the night falls- Eddy Kim & It's you- Henry Lau) that was ending the episodes. This drama has all the feels and anyone who likes some suspense, romance, drama and comedy you'll get it all in one package. Not to mention the chemistry between the two main characters was just perfect, it wasn't over the top and was just right again making it realistic. Definitely a must-watch!!!
