Basically almost identical plot: blond haired green eyed woman discovers that it was her husband, a handsome black-haired blue eyed stoic looking duke, who secretly caused her family's ruin and her father's death behind her back, so she commits suicide and they both go back in time, where she reunites with the other man who tried to help her in the past life (there's even the coincidence this other FL was even also pregnant not long before the time-reversal...). Only difference is time-regression in this other story is delayed to take place in chapter 21, so that readers can witness the progression of events (which happen much faster in terms of years) with only a slight variation in the order of events: the husband woos her before their marriage, then secretly goes and falsely accuses her father of treason, causing his ruin and death, so that he can then play dumb and pretend to come to her and rescue her, after her father's execution, like a knight in shining armor, in order to induce her to marry him, as part of his own secret agenda... only for the love rival to come and help the FL find out the truth not long after the wedding... (thus, making her actual marriage to garbage husband last only a few months at best... instead of seven years), and then after the husband tries to confine her and kills some of the people who try to help her escape, and she has miscarriage (of the baby conceived BEFORE she found out the truth), the story moves right on to the part of the suicide, and on to the time-reversal... Thus, she doesn't spend seven years of "torture marriage" to him in this one (even though she did marry him not just for love and because she didn't yet know the truth, but also because she had no choice in order to escape the life of poverty and slavery as an executed traitor's daughter, but still...) Same, same, same
