I have never been super emotional by watching a kdrama. I've watched all the popular and high-rating kdramas but this.... is a MASTERPIECE that all kdrama fans should know about. Even the OST is pure haven! This is a roller-coaster of emotions as each episode emits a certain feeling, whether it be sorrow, joy, longing, fear, or love. The plot is deep as the Mariana Trench and you'll never be bored, I promise.
SPOILER ALERT: Don't put your hopes up especially during the last 2 episodes. And prepare any piece of clothing to wipe your face, because once the line "It's alright, it's alright" comes, expect tears uncontrollably streaming down.
