Kairos is the baby drama when Signal x Nine has a crossover. Honestly, I'm half tuned out from the show, maybe it's the holiday buzz and I realized I'm not in a mood right now for a suspense drama. Or I'm just the hopeless romantic that needs a good romance to anchor me to a non-romance show (like Nine). But even through that, Kairos is a solid show and they did something different from the usual 'whodunit' drama.

The suspense does not come from identifying twist after twist of who the baddies are, But from how the protagonists go about trying to pass every hurdle and change a tragic happening in the past or the future. I like Lee Se Yeong's dual role in Hwayugi and she doesn't disappoint here. All actors are commendable, but Winner guy Kang Seung Yoon really stood out to me.

One quibble I have is how calm Shin Sung Rok's character accepted his wife's 'extracurricular' activities. Lastly this is the rare drama that stuck to its own rules until the end, even if they have to keep the suspense going.
