"Tomorrow..." is more of romantic/fantasy drama than real life story like "1 litre.." but somehow I found them very simmilar..
They both makes you rethink your actions and priorites in life.
Life that can be very short, fragile and unjustice.

Yeo Jin Goo plays the main male lead in both.
Both have a mystery and supernatural elements.
Similiar in a sense that both drama's have two parts in them.
Circle has part 1 Beta Project set in 2017 and part 2 Grand New World set in 2037.
Reunited Words has parts in the past in 2005 and parts in 2017, however not in a set sequence like Circle.

Both dramas involve a person "traveling through time" in a way.
I'm not sure if Reunited Worlds has anything to do with time-traveling yet but it could.

Both dramas involve a person "traveling through time" in a way.
In Hit the Top the male lead travels from the past into the future and doesn't know why. He doesn't realize he's in 2017 at first but he does after a while.
In Reunited Worlds the male lead wakes up in 2017 thinking he's still in 2005 where he was still a high school student. He doesn't realize this at first.
Hit the Top is different since it's a time traveling drama.
Reunited Worlds seems more supernatural.

It's the original Korean version of the show.
Both female actresses have to play the roles of two different people since she is playing twins.

If you like wonderful mystery dramas, you will like it.

Both are surprising japanese TV dramas with great plot twist in the end.

- The ML of Cambrian Period works as a masked killer under his adopted father who is the leader of a criminal gang. You would never expect an innocent, puppy like, pretty boy behind the mask.
- Both have action, crime, mystery, romance

Both involve time travel and the female leads are doctors. In Faith, the male lead brings the female to the past. In LUTYN, the male lead is sent into the future.

Both are romance historical dramas and sorta have the same method of time travel.

this drama targets the same audience. Light romantic work.
i thing you might like it better than smiling pasta.

it is also a light fun drama. I would recommend to anyone searching to watch romance.

they're both about time travel or connection with the past and or the future

This two dramas are very similar. The main couple they are from rival countries. She saved his life when they were kids. Both main girls have something they wear to make the male lead recognize the girl, in general and I it was a jade hairpin but in The King's Woman it is a half cirlce jade necklace. The male lead forces marriage with the main girl. The main girl is in love with someone else in the beginning. The only difference so far is that the main guy is king in this drama but in General and I he was a general, also the female lead was a female strategist in General and I but in this drama she is a swordfighter.

it might be interesting to see for a fantasy fan. a lot of magic and good romance.

the main lead is from a fantasy world.
he also has superpowers
the plot is interesting
