Wrong Groom, Doomed Clan

Su Jinning has lived this year once already. In the life she remembers, the marriage arranged for her ended with the Su household condemned and executed together. She wakes on a day before the betrothal is fixed, with all of that still in her head. What she changes is the man. She refuses the match she had the first time and pushes for a different one, on the reasoning that the marriage is what ruined the house. Her half-sister turns the switch to her own use, a minister with weight at court leans on the family from the other side, and Su Jinning ends up married to someone she did not pick. The same charge builds against the Su family, and it carries a death sentence for everyone in it. She works from inside the marriage to sort out which man she should have chosen and which of the moves against her house came from her half-sister and which from the minister.
