Just like the title says I'm searching for dramas similar to Reset (cdrama) . I love every single episode of it..the sub romance, teamwork, the ending all of it was top notch! 

Yet it's being years still haven't found anything similar to it,, it would be so nice if someone help me find one. 

(Btw there was one movie which was quite similar & I loved it too,, A Day Korean movie)

Actually Triage is quite similar to Reset, but it's a BL drama.

And maybe Erased.

There's also a drama version but I haven't watch it. I read the manga and watch the anime but I remember the ending is different from the movie (but I may remember wrong).

Put some less thrilling but still has mystery solving and death on it but some are focusing more on the romance, please check the trailer first:

Love in Time

Lovely Runner

Someday or One Day

And some I haven't finished (not because they're bad):

Shining for One Thing

Tomorrow with You

 autumn iris:
Lovely Runner

i did loved this one" and i watched "erased" too (anime) it was pretty good!

I know, the anime was so great. But the movie is... really, literal definition of boku dake ga inai machi. Perhaps you should try the drama version Boku Dake ga Inai Machi, since the rating is better. I also put it on my ptw. I just know it exist.

Hope you'll also like the others.
