Didn't she attempt to run away the second time? Third time, she attempted to act as a spy because she doesn't have power and would at least like her life and her mother's be spared.
It's hard to build up courage and power against a powerhouse until she confirmed that's the only method. She's considered wise in the 4th life because she actually built up the experience.
To be honest i didn't not read much after she said it took her 3 lifes to realize he betrayed him... so knowing her type, she will probably try to extract her revenge throughout the story only to give forgiveness talk at the end , walking away with boyfriend or maybe boyfriends she got in her arms. Not my cup of tea ╮( ̄▽ ̄)╭
I think she ended up killing herself in the 4th life cause she keeps falling for his trap.
The 4 lives she lived, she said “He lured me with his sweet words then discard me without hesitation once I outlived my usefulness” and that the 4th time will be the last(then ending herself)
So while she did try to change the future, she keeps falling for his trap even though she kinda have the upper hand of “knowing the future” cause she keeps going back to her 12 year old self

I drop it a while back cause ch. 1 pissed me off. What you mean that man killed you 4 times to realized he’s not gonna change no matter what you do shii maybe I’ll it pick up again when it’s complete
