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)

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.
