"A relationship that defies time" - Masterpiece. Story is excellent and there is a unique display in regards to the concept of time travelling. Whether it was a heartwarming or saddening moment, I shed a couple tears as this series drew out a variety of emotions from within. 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. The soundtrack is incredible. The romance and comedy in this series was nothing short of perfection. Not only did this work of art entertain me, but it gave me hope, and I am genuinely sad that it is over :(
