there is no doubt to talk about acting as usual perfect
OMG FL DONE ACTION YOU CANT SEE ANY OTHER KOREAN DRAMA
TRP is also good in Korea but many of them give low rating only because they want to watch romantic series but in this series you will know all about time travel, paradox, warm hole for these thing to understand you need a brain so many of them not thats why they give low rating
UNPRECTABLE yes you cant predict thats make me more interesting to watch more episode
even they shows us about mental health issue also
I Love this you need focus to understand thats it
after watching I can talk about YAAA I KNOW ABOUT TIME TRAVEL
I wish there would be 2nd season also
