I watched this drama consistently till the 10th episode and then kept skipping till the last episode. it started off strong with characters who piqued my interest, this unfortunately lasted only for the first 7 episodes and went downhill from there. This drama should have ben a movie because it was a story which could have been told in 2 hours.
The writer was grasping at straws with the premise for suspense, nothing was said about the person who hit the comatose guy, also the second ML wasn't racing against himself, so why was there no mention of the others involved. if you are watching for romance, this will be a disappointing watch because neither the main nor second leads had chemistry between them.
