Why is this drama not talked about
It had everything from great actors, character development,& wonderful cinematography. Scenes at Cuba were cherry on the top
To be Frank the drama had no plot or storyline, rather it focuses on how lives changed.

I am personally, not a fan of age gap stories, but this is how you execute a piece, that someone who hates the trope, is forced to love it.
Also, the beautiful art at the start and end of each episode was so beautiful and kinda unique, and had a distinct meaning.

Everyone complained about the slow pace of the drama, but for me it was more than good. It is something that should be absorbed slowly and steadily.
It was great to see a female CEO and young recruit falling in love, total opposite of the usual roles in dramas.

The negative part of the drama was the arc of supporting characters. None of them had a proper dimension. Even the villians were too plane. Also the way the story unfolded after the 14th episode seemed forced. The reason for separation was too bleh, inspite of so many villains.

Overall, a good watch for hopeless romantics.
