Kairos is a drama that I love to rewatch in my holiday season. It's really a thriller drama that deserved a baeksang. I started to watch because the teaser is so good and the genre is my style. If you love Signal, you will also love Kairos.

What I like :
- I like the plot. The plot was made me sit of the edge. I loves whenever the lead's decision make a butterfly effect in their fate. Something changed in the past will affect the future.
- The cast is really brilliant. Shin Sung Rok, Lee Seyoung, Ahn Bohyun and Nam gyuri really played their character really well. I know the most shining star is Shin Sung Rok, but the other really showed their own charm. Shin Sung Rok lloked really cool when he played as present and future Seojin. He gave a different emotion and aura in two characters with different times. Seojin was never eaten in the drama and lose his child that made me shows empathy to him.

What I don't like :
- Sometimes the screen is a bit shaky
