The story is light-hearted and the casts chemistry is superb. If you watch touch your heart, you will know the feeling. Yumi’s Cells is more about her life and her cells. This is so better than any recent rom-com dramas, i'm not kidding. If you don't like it then it’s your loss because you can also get lessons from it which usually happened irl. Same with Touch Your Heart you will also moved with this drama.
