I would love if it had additional time travel or body swap or any other fantasy element to it.

Romance doesn't need to be at focus. Mystery thriller should be the important part.

Ending should be conclusive and either happy or hopefully happy or time skip happy ending and shouldn't feel rushed. I hate open or ambiguous ending (so please don't recommend any such of those).

-Eg  of k drama endings which i prefer the reccomendation to be closer to -

* Tunnel - while ending could be better, but it is acceptable level.
* Welcome 2 life - i dislike the other timeline ending not being explained, but rest was fine. So still acceptable.
* Reset - it a c drama, but ending acceptable even if it had few problems

More Prefered/ideal ending would be something closer j drama like "Erased" or even better "Alice in Wonderland"

-Eg of k drama ending which i don't prefer recommendation to be closer to -

* Flower of Evil - please no amnesia crap at the ending especially no anguish time skip  (another eg of crappy anguish time skip ending is Pinocchio). So please don't rec me discount happy ending which come at last sec after a huge time skip dedicated for anguish
* Train - another eg of ending with anguish time skip using a last minute plot twist.
* Squid game - please no sequal bait or tragic ending like this

Someday or One Day - this is a really really good mystery/time travel/thriller/ romance  drama. It also has the body swap theme. Has a good ending and highly recommend it to you and would say you should give this a try the most ;)

Others;

  • Life on Mars
  • Kairos or Gods gift 14 days - both dramas are quite similar, although the first one is more newish and thus more popular. Both are well done, both have time travel as theme. 
  • 365: Repeat the year - I really liked this one. There is not really romance in it though but the main pair has great chemistry
  • Nine Times Time Travel
  • Meet me @1006 - so this is less thriller and more focused on the romance aspect but it does have a case and it does have time travel as a theme

Why does most of them have open ending tag?

Why does most of them have open ending tag?

tell me which one because as far as I know and remember no one had any open ending. If one has one and I accidentally forgot I apologise but I was very adamant to not include those that had an open ending otherwise I would have recommend you Signal right away since I do believe this is the absolut best drama produced.

Edit: I checked. Non have an open ending tag. Two commenters pointed out that there is an end that has room for interpretation with "Someday or One Day" and "Life of Mars" . But that is a subjective assumption. I watched both and for me it did not feel like it could be classified as open ending.
