Well, I really tried liking this drama but it didn't work out. I tried giving it time, saying that it would be okay, that the story will be better from episode 10, guess what, it didn't get better. After each episode, I started to think about if it is worth it, and finally, after 16 painful  episodes, I gave in. I just couldn't bear it anymore. The only thing I did like about this drama was Henry, and that's all.  Okay, I did like the acting, the actors did play really well.
About the parts I didn't like.....
Not only that the beginning was sad and really emotional, but in most of the episodes, at least 4 times, the two main characters cried. I understand, it is a drama, it is normal for them to cry a lot, but it is not normal to cry a million times in each and one episode. Seriously now, after watching an episode, I felt so sad and depressed, it made me feel weird and I didn't like that. I usually watch K-dramas to feel somehow better, not to get depressed.
The story itself was kind of weird, it started with abuse and with emotional scenes that made me not want to continue watching. But I didn't give up, and I kept watching even through I hated it, I didn't want to start a new episode, I was searching for something to do instead of watching it.
I personally don't recommend watching this drama, only if you want to get upset and depressed.
