Each of the 20 episodes is between 9-14 minutes long. However, there is about a two-minute recap at the beginning of each episode and 2-3 minutes of credits at the end of each episode, so these episodes are REALLY short. Unfortunately, this leads to not enough content in this drama.

I was grabbed by the idea. The concept of him remembering everything, and her remembering nothing was a very interesting one to me. But there really wasn't enough time to adequately flesh this out. We saw him living out a tragedy in his past, and we saw repeatedly how he remembered everyone's name, but there was a BIG link to the story that he didn't remember until almost the last episode, so how can you say he remembers everything. She doesn't mention until a few episodes in that she only remembers things for a month and then her memories reset

I would have liked to have seen how she deals with having to reset her memories every month, and how her friends deal with it. That would have been fascinating. This wasn't addressed at all.

The ending is very abrupt. Stay and watch the ending credits on the last episode, it gives a "wrap up" interview with the two leads that is cute and attempts to end the show in a more meaningful way.

I was so disappointed in the execution of this drama, it had such potential. That being said, at least it wasn't a LOT of time wasted.
