I like the friendship story between Yi Yong and Guang Yan. Their interaction is cute, natural and well acted (bickering and snipe remarks). I find Guang Yan extremely adorable.

I also felt for Yi Yong loss of his father and his regrets. It is this story that also keeps me watching to the end.

Overall, it is quite a well done show, not draggy and to the point. The individual cast and scripts are appropriate and well acted.

The big problem is flat and shallow story. Yi Yong regrets and final meeting with his father is short-changed. Certain scenes and his actions in the middle of the shows are extremely well done and touching. This is something this show has directed well over most drama. No overtalking. No words is needed, action speaks louder. And it just makes you tear when he does something without explaining. But the final meeting with his father and overall story of his regrets is lacking, not complete, not right and no good closure.

Next, the obsession and loss stories, and the stories' various characters are also dull and shallow. They should compliment it to develop Yi Yong regrets on his father story but no except maybe a little bit. Thus, it become boring and repetitive from second half despite the cast's good acting. And perhaps, due to no idea or research, the story arch was the usual thrilling bad guy plot, its common and not in the spirit of this story. This ending is a let down.

The reason this show scores 5 is because it failed to develop the character nor come out good thrilling plots. Most shows nowadays did not develop character - how they grown and change (except maybe Till the end of the moon which is badly directed). Instead, more thrilling plots or fantasy are used to hype up the story. This show is lackluster on both aspects but it scores on the interaction and relationship between the characters, especially the 2 main leads.
