I like the plot. ( Drama after 11-13 episodes was boring but still I liked the plot)

ML dies, FL goes back in time to prevent death of her husband, but she must sacrifice something instead.

She goes back in time before she have met her husband, so her love doesn't remeber her, but he is suprised that she knows informations and things which nobody shouldn't know. ( She know it bc he told her in the future)

You can check Train.
Plot kind of similar. FL gets killed. ML travels between parallel universes to save her and solve the mystery of a serial murder case.

Also can you put the MDL link of the drama (Deja Vu (2013)) you mentioned? Couldn't find it. I found the plot interesting and want to check it out.
NVM, found it. why was I assuming it to be a koran drama, I wonder

Someday or One Day (2019)

Do you require death? There are some excellent "redo" fantasies about lives and relationships that went bad.

Taiwan has produced some good ones. I particularly like Love, Timeless.

It doesn't have to be death, but I would prefer FL to go back in time

I'm guessing it's this one.  https://mydramalist.com/8336-deja-vu

Yeah, found it. I didn't scroll down at first. 


On topic, ML/FL or both goes back time to change their life. If you want  things like that then you can check these too
Familiar Wife  -  Relationship in disarray. ML goes back time, changes life but destiny.
Shitteru Waifu  -Japanese remake of "Familiar Wife". My preferable one, shorter(duration) than the og korean one but less dragging of plot.
Go Back Couple - Haven't watched it myself yet. But according to synopsis couple travel back time to their university life to rediscover their relationship.

Tomorrow With You is another one related to time travel. But here too ML is the time traveler.
He does go back time to save the FL but there wasn't any genuine romantic feeling or reason behind it (initially), It's more of personal reason as both leads were somehow connected via fate.

I highly recommend you Some Day or One Day as well. It is exactly what you are looking for.
You have a female lead who is confronted with the death of her boyfriend, but she gets a music cassette send to her and then characters and timelines come all juggled up.

It is a superb drama with great acting. It is also a taiwanese drama :) Do give it a try. 

You will most definitely enjoy someday or one day. Its been said quite a bit but i want to reemphasize how badly youshould watch. that drama - im still looking for something that is up to par with it :'(

I found something similar to Deja Vu

It's chinese drama "See you again" ( 2019)

I watched this in one day haha

It wasn't masterpiece, but I enjoyed with this and even cried so It wasn't too bad.

I also watched Reset life 2019 and Don't disturb my studies and It was okay.  

In each of these three dramas ( Reset Life, Don't disturb my studies and See you again 2019), FL tried to prevent something from happening.  (Not necessarily death)
