Hello, so I forgot the title of this novel where the MC is someone with a system about to get married to a guy who also is contracted with the system. She has feelings for the guy but he doesn't, so she gets tired of chasing him for hundreds of years and decides to give up. She dies in that world with the guy she loved calling her name. She returns to the space where she has to decide whether to ascend or return to her world, she wants to ascend but the system told her she can't so she decides to go back to her world. When she was about to go home, something goes wrong and she gets thrown to lots of worlds without a system. Please help, I've been looking for this novel for 2 hours and I still can't remember what the title is. Thank you very much in advance.
