It's very simple, this series does everything and can do everything. Romance is my favorite romance that I've seen in my life personally to this day, since I finished this series I'm touched by a gigantic nostalgia.

The actors are great and their levels are amazing, their chemistry is on a level that I don't think I've ever seen in a series of romance. It's just exceptional. The secondary characters? It's simple I would like them as members of my family so endearing they are.
The music is amazing and unforgettable, it always comes at the right time and is very touching. They've obviously been on my Spotify list ever since.
The plot is very good and personally I found it really interesting.
The most successful thing about this masterpiece is for me the main romance and the chemistry between them as well as with all the characters. It's just magic.
This series showed me scenes that I would never forget. I hadn't even finished the show that I knew I was going to look at it many times in my life.
As for the emotion it gives it is very simple I cried from episode 4 to episode 16.

Sometimes I literally cried because the characters were just too endearing while the scene wasn't really sad...
In addition, the jokes and funny scenes are really funny and frankly it's too good because I'm not one to like shows that are too much in comedy. Attention I'm not saying that this series is a series of comedy but I'm just saying that the funny scène are really fun and it's cool.

Finally, I'd like to tell you that I don't recommend any drama as much as this one. If you're looking for a super touching story with amazing characters and a incredible development this series is for you.

Actually if you're looking for something magical that you won't forget Crash landing On You IS THE THINGS YOU SHOULD WATCH.
Please go and look at this masterpiece.
