Just got a recommendation from a friend to watch this, and definitely not regret it. It's really a good drama to watch and yes addictive for sure. Therefore, I only spent 2 days to watch it.

ML is so damn hot and interesting - kind of a cold and arrogant one that is possessive towards the FL. He own a security company that provide bodyguard or hosting an event (something like that). And the FL is so pretty, adorable, and smart. She works as a theater artist. They met because of a dangerous situation (which is you will get the explanation later) before and fall in love until they separate it cause of life and death situation. Then finally after 5 years, they met again, get back together, and solve the problems that hasn't done it from five years before.
The second lead couple also got an interesting story, and I just can't forget the daughter of SML. She was too cute and smart.

A great storyline, awesome cast, good chemistry between the couples. What can we ask more? Overall, totally worth it and enjoyable. Really recommend you guys to watch it! Short and not draggy at all.
