More details on the novel that I’m looking for: Female mc transmigrates to different worlds in order to win the medical system in the system’s lottery When she finally won the medical system, it turns out that she cannot use it herself because she is in a coma, thus she has to give it to someone else She entrusts the medical system to her cousin because the cousin was the one who always visits her in the hospital The female cousin did not want to save her so she had to haunt her and threaten to take away the medical system if the cousin doesn’t save her One memorable arc was when she was actually a rich family’s daughter but she got swapped with a girl from a misogynistic poor family and her original family didn’t want to take her back. She had to threaten them in order to take her back but her family thought she was ungrateful to the poor family that took care of her. That was until her life with her grandmother was witnessed by the book’s original ml, her biological brother, and the sister who got swapped with her and who should be living the hard life with her original family. They watched her toil the fields from early in the morning working nonstop until nighttime. Any help would be greatly appreciated!
