To keep it short, this show had some potential but wasn't the best executed. There were a few plot lines that I didn't like and could've been better if written differently. Also, I'm never one to like slow burns, which turned me off, too.
I liked Wan's character and how she did what she wanted. I also loved Mali and Sam! Their comedic timing was perfect; always making me laugh. I loved the whole storyline of the fours' friendship, it was heartwarming.
It wasn't anything crazy and not something I'd watch again, but it was still enjoyable. I wouldn't recommend anyone to watch this drama though.
