The first scene might probably be her never continuing the deed. At that time she already has feelings for him, so it means that she didn't continue it because she loves him, but she did tried to. And It was never shown that the ml really did died, when fl tried to kill him at her first life( the first scene that you were talking about).
This latest flashback of fl is the aftermath of her not killing the ml, which was her being killed by the curse instead. In simple words, its the continuation ~(●'◡'●)ノ
Ok wait in the first chapter she “killed/stabbed” her husband but now she didn’t stab him????? And died in her bed alone??!!!!!! Someone please explain
