I loved everything about this film, from its plot, actors, and its theme. It definitely exceeded my expectations. FYI, I don't write reviews hence this is my first time. You ask me why I decided to do it, well this movie is worth writing for. IT'S THAT GOOD! I highly praise D.O from EXO, his versatility will bring him success (it already did) but for the future to come, I hope he does more dramas because he's too talented not to be exposed again. And of course, Mr. Jo Jung-suk, he did wonderfully portraying his role, I cried my eyes out for this film. WITH THAT SAID, I swear to God WATCH THIS FILM!!!
