Maybe many will like the first one more as the story focuses on just the two main leads falling in love, but if you are looking more than just the two couples loving scenes, you will probably enjoy this more!

In terms of production, I think they got more budget for this series so the scenes and cameos in this series are in bigger scale and VERY MUCH better!!!!

In terms of storyline, I prefer this one than EL1 as well because Cheng Cheng's hidden mission parts just made the show more exciting, you will be worried that he might get caught or die or whatsover, so that will make you go on and on watching the next episode.
(However, it would be even better if their whole series is in modern world, not just the first few episodes haha! I enjoyed watching them in the modern world more)

Also, I think Liu Shang's actor selection wasn't really a good choice as it always made me felt like they are not the same person. Not because they don't look alike (as they were not supposed to look alike), but the actor didn't really catch the details on how Cheng Cheng smiles, hand posture or expression when talking to Tan Er... hmmm probably the only part that this show is lacking.

Regardless, looking forward to EL3! Because I just wanted to watch the couple again.
