The ending is better than before ;)

FL seeks revenge assuming another identity (gains a better husband in the process)

FL seeks revenge through a second chance in time (she ends up with a better and understanding man)

FL seeks revenge whilst concealing her profession (eventually ends up with the man she was trying to kill)

FL seeks redemption after her death. Second chance back into the past and she attempts to change all the bad things she had done (Her chemistry with all the characters are great and her killer became her lover)

FL seeks revenge by going back in time (Similar to marry my husband) (gets a great husband by the end)

FL tries to change the past to avoid her death (She still ends up with her husband but on better terms)

This one is a little different. Technically the FL lives the identity of another person in historical records and aims to change history by humanising the tyrannical king of the past (she didn't realise who it was until ages later tho)

FL is a writer who goes into her novel and as a side character she attempts to change the flow of the novel (Not the happiest ending but her fiance becomes better iykyk)

ML's soul enters another body and he seeks revenge for the body's owner

FL coincidentally goes back in time due to the mistake of the ML. FL tries to change the fate of her parents because she thought her dad was a bad person to her mom. Both the ML and FL figure out about the murders that happened during that time and try to change it as the ML and the Fl's mother gets killed by the same person later on. (The two became a couple and had a son later in the future)

FL goes back in time to change the life of her favourite idol after he dies in present time. Multiple returns to the past happens because he seems to die everytime she returned to the present. (She ends up getting married to said idol)

Both ML and FL unintentionally go back in time (to their parents' time). Knowing this they try to:

- Change ML's dad's issue of hearing loss

- FL tries to matchmake her mom to someone else

In the end the two get together but their attempts at the above slightly change the future.
