Hi there,

So I've been watching k-dramas for a few years now and I feel like I can't find anything that appeals to me anymore, k-drama wise, so, I stopped watching a few months back but, now I feel like getting back into watching some newer dramas, specifically any new or recent time travel dramas would be amazing.

Thank you.

for time travel check out Reunited Worlds, it's pretty interesting and just started airing recently 
TIME-TRAVEL DRAMA  

We must distinguish between drama WHERE time-travel is the cause that triggers everything BUT it's not the MAIN topic of the plot. 
And drama WHERE the plot is completely tied up to time-travel, even if there is not actually a time-traveller.

I don't know what you like, so I will put all 2016-2017 k-drama that deal with time-travel

  • TUNNEL (crime base on a true korean serial killer, the detective in charge travel to future only to discover the serial killer is still around.) 
  • HIT THE TOP (hip hop top star in '90 travel to future and fine romance, friendship and family and a bit of mystery)
  • REUNITED WORLDS (a student wake up in the future, school, romance, friendship, it's actually still airing)
  • MY ONLY LOVE SONG (a top star suddenly goes back in time to the Goguryeo era)
  • MOON LOVERS: SCARLET HEART RYEO (a woman travel back to the Goryeo Dynasty of Korea, tragic love)
  • TOMORROW WITH YOU (a man who has the ability to time travel and try to change is future into a happy one)

there is not actually a person who travel time, but the plot is tide up on past and future.
  • CIRCLE (sci-fi, the plot develops between past and future)
  • SIGNAL (crime base on a true korean serial killer, two detective speak from past and future with a radio)
  • SAIMDANG LIGHT'S DIARY (An art history professor find the secret diary of Shin Saimdang a Korean artist in 1500, half of the plot is set in 1500 and half in modern day)
