Masterpiece. Im Sol and Sun-jae perfectly played their roles, I loved the relationship and chemistry both leads had. The supporting cast was phenomenal especially Tae-sung and In-hyuk. Plot was excellent and there was a unique display in regards to the concept of time travelling. This series drew out a variety of emotions from me as I started tearing up at both the saddening and heartwarming moments, and began laughing out loud during the comedy scenes. The romance in this series was nothing short of perfection. The Soundtrack is Incredible. Not only did this work of art entertain me, but it gave me hope, and I am genuinely sad that it is over :(
