@Angular admittedly looking back at them, my comments were extremely negative and I should have just skipped the story.
For this comment, I did not mean it in a sexual way whatsoever, just that the sister and MLs family will always come before FL. Sure when they are younger that makes sense but what about later when they marry? Would you live with someone who doesn't even put you as first in everything?
Even without this, there is a worrying trend in korean reincarnation stories where completely average (not evil) FLs have to relive horrible traumatic experiences and go back to their bottom of the barrel MLs because of idk what reason, just that he used to be a male lead? Couple it up with FL not having literally anyone in her corner either, not family, not friends, not even a dog or a cat to hug is just pitiful.
However women act in these stories, they are still put through most miserable experiences and then they are shipped back to repeat the suffering cycle while struggling for it to not repeat. In the end, a completely wrung-out, jaded character gets their pyrrhic victory and they end up with someone who abandoned them first.
