Elated when I found out Lee Dong Wook and Yoo In-na got casted as a Main couple ever since watching "Goblin." I've never been this invested in a loveteam and am looking forward to more projects of them as a Main couple again. There's no denying their chemistry (which I feel so strongly about my heart could burst with adoration) and how well they make their characters blend in.
tldr: "Touch Your Heart" has truly served its meaning to its title. It has touched so many hearts including mine, and their OSTs (Chen, WENDY, and 1415 are my faves) add to the lovely and charming appeal of this drama.
More blessings for these 2!
