Review Detail of xpired_sin in After Transmigration, I Unexpectedly Eloped with the Grand General

This reminds me of another story where the fiancé didn’t show up in time for the marriage and she was forced to find another person to marry or end up with a random person or something. She got together with some war hero/prince who had a case of amnesia and was going through some susceptible period by accident. Instead of mechs she was a chef and was bringing back real food to the interstellar era. This is slightly different but the other seemed better written.
