This series did not seem interesting, but decided to watch it since there's nothing good to watch lately. I was looking for a light-hearted rom-com. This had potential failed due to the unlikeable female lead and lack of chemistry between the leads. I was so tempted to drop during every episode, but I suffered thru the whole thing, skipping A LOT.

PROS:
- Two very good looking leads
- ML's grandfather was the best character, genuine and likeable

CONS:
- FL is unbearable. Several other reviewers had the same perspective - she was just not worth all the efforts put in by the ML. She was arrogant, overly stubborn, manipulative, and downright rude at times. She could not convey any redeeming qualities other than intelligence and ambition. She is stunningly gorgeous (probably one of the most beautiful actresses in Cdramas) - but this is the 3rd time I've seen this actress in a series, she is NOT a good actress.
- ML acting wasn't terrible but the character was inconsistent. He started out as a tough, stoic rescue mission leader, former counter-terrorism unit (almost 30 yrs old), but then somehow evolved into a wimpy, love-struck teenager with no boundaries. Followed the FL around like a puppy, tolerated all her insults and games w/out faulting her.
- Leads w/ NO chemistry at all
- All support actors were super annoying, especially the 2nd FL, the BFF. She was intolerable too. And the outdated trope that I can't stand...a good looking person, add glasses to make them look nerdy like the 'ugly duckling' and do makeover removing glasses they suddenly become a beautiful swan. Insulting to viewers.

Dont' waste your time
