10/10 K-drama. That's it. This action drama is really really good! Everything in this drama will make you feel thrilled, cry, and think at the same time! and THE TWIST!! Omg I didn't expect it. I thought I already know what may happen in the next episodes but I was wrong! EVERYTHING IS PERFECT!! The songs, the actors, the characters, the plot, the scenes, EVERYTHINGGGG~ Definitely one of my favorite drama that I've watched this 2021! Watch it guys! Yes, the ending is not that satisfying but in my opinion this drama is not enough for season 1 only. Definitely needs a second season to give a better understanding and a better downfall for the villain in this story. And to justify the death of the victims of the flight B357. So yeah I still think the ending is perfect.

Definitely worth it and yes, I'll recommend this drama for you to watch.
