The thing that makes this drama unique is that it incorporates a lot of flashbacks to tell the story of the female main lead. The FL is currently in a coma at the present, but she's supposed to be getting married to her fiance whom she met in college. The focal point of this drama is not about the accident or how she got into that predicament. After all, she's in a coma for most of the episodes and she lives through flashbacks that tell the story of how she and her friends met. Moreover, this drama's purpose is to highlight the people who are special to the FL. Very clearly, all the people in her life have a piece of her heart and she lives through them, even though they may not realize their significance.

This drama is confusing in that it does not introduce the characters in the beginning nor does it explicitly show how each character has grown from the past to the present. It's meant to build on the viewer's personal experiences and memories, especially for the sentimental ones who look back on their college days and wonder where the people we used to know have gone. During this drama, I wondered: would I ever be able to reconnect with my old acquaintances and friends again? This drama is artistically done and is up to your interpretation of what the moral of this drama is. For me, it's reminiscent of the people who I used to know but only exist in my memories now. Most importantly, it reminds me that even though these people may not be in my life anymore, their impact on me is forever.
