On top of my head this drama the drama's premise initially reminded me of My Love From The Star, another drama which I really like. However, once you get past the fact it's rom-com between an alien and human...it's pretty much completely different.

The thing the drove this drama is primarily the FL. Chai Xiaoqi is a quirky and naive alien character who has this fish out of water curiosity to her that behaving unnaturally that lead to rather funny and interesting moments. She came to earth on a simple mission to study plant life here, I guess, but one day while trying to save the ML she lost her annunciator that help transmit a signal back to her home planet to retrieve. Turns out it was embedded into the ML's heart during the car explosion which knock her into river nearby. The ML is a character who suffers from amnesia, in which every time it rains...he'll forget the women in his life. This made the ML extremely difficult to start any meaningful relationship in his life, that is until he met the FL. Something attracted him to her and eventually he found out that he could actually remember her after one of the rainstorm, so he suspect she might be pivotal to help him cure his illness. Once you get past the extremely weird premise, you'll find a really quirky, fun, light-hearted romance drama.

Pros:
-Likeable main leads and supporting characters. Lots of cute moment. ML
-Cute relationship between the FL and 2nd ML. Although eventually 2ML fell in love with FL, FL has always treated him like a buddy and good friend.
-SML is the ML's brother, despite ML constantly being jealous of 2nd ML whenever he's chummy with FL, he love and supported him.
-FL live with a restaurant owner who, herself, is pretty funny

Cons
- Wacky premise that's really well explained...neither her alien origin or his amnesia make much sense for me even by the end of it.
- Tons of cliches but fortunately for me it's not too overbearing. This might be a major cons to some of you.
- No well-developed antagonist. There are three primary antagonist in the show: the step-mom (almost birth mom of 2nd ML) and her brother, the crazy ex-gf, and the weird scientist. And none of them make any sense, imo. They're just there to bring obstacle between the main couple really.


It's hard to describe what makes this stands out amongst the other rom-com. But I really enjoy the main couple and their romance and their moments together. So, imo, if you can buy into the main leads' romance, you'll enjoy this a lot. It could've been less then 28 episode, imo but it wasn't too long that it truly bothered me.
