I’m pretty sure I’ve seen the news somewhere about Shin Sung Rok, Lee Se Young and Ahn Bo Hyun as casts in a new drama, but I’ve never really pay attention to it, never was I interested in watching this drama. Hear me out, the writer, the casts (main and supporting) , the plot, the storyline, the everything there's no slip at all, and they say nothing is perfect but I think Kairos is perfect, at least a 99.9% perfection. Because the tight plot, fast plot and to the point of the story. Music is on point for the genre, I guarantee that every episode will always make you tense, goosebumps and want to know what really happened. The last few episodes have an incredible plot twist. not unexpected. It's a classic drama in its style: thriller and suspense 100%.
