It's a true blue Asian drama! He's so cold and somber. She's like a ray of sunshine on a rainy day. And of course, they met years ago, but forgot. Especially, when there is a major car accident involved. Give them time. She has no luck. He has all the luck (or does he?) And still, she's a ray of hope in the mad mad world. Throw in some electricity generated from the heart and you've got a fantasy romance to watch. Just 36 episodes (about 45 min. or less).
I have always been fond of Fair Xing. She was wonderful in the MASTER DEVIL DO NOT KISS ME series (1 & 2). She was sincere and witty in Put Your Head On My Shoulder and My Little Happiness.
While Allen Ren (32) has been making dramas since 2016. Once upon a time, he was in a Chinese/Korean boyband Super Boy & Korean Star but it didn't last. Also at that time he was with Nie Haun and they broke up, but they have made up and are married and have a family. (Sometimes, I wonder about the drama these actors go through with their fans and the entertainment world). Still, he's managed to be in some epic period-piece dramas and fantasy dramas like The Glory of Tang Dynasty 1 & 2.
