It is a really great drama worth to watch in your spare time. I binge watch it for a total of five days .. But if you have more time to spare watching it will be like 2-3 days because the first few episodes will really hook you in watching all of the 46 episodes. I am not a fan of long episode drama but this drama is definitely worth it.
Here are the reasons:

1. Story- the storyline here is superb. I think they really put an effort into making it. I feel that there is no filler here(maybe a little bit of flashback here and there). The story doesn't just make one character shine but all of them.. Every episodes are amazing. So if you think of skipping some episodes please don't you will regret it..

2. Acting cast- The actors here portray their role very well. Even the side characters, supporting characters, antagonist up to the main cast. One of the reason i watch it is because of the handsome actors and pretty actresses. Also, love the couples here.. not just for the main couple but also the supporting couples..

3. music- i feel that they only use 1 music here(the opening song) through the whole 46 episodes. even in scenes for action and sad scenes.. but i don't know why the opening song still fits on the scene.. maybe because i am just hook into watching it hehehe..

4.The Ending- i think most people will see it as a happy ending.. But some will see it as a sad ending if you are into romance because the male lead doesn't end up with anyone here.. You know the typical chinese drama.. If you are not into death don't watch it because this drama has a lot of it. I am not a fan of death too but i think those deaths are required to make it more exciting..

Overall... it is a must see drama that worth spending your time in the 46 episodes.
