I forgot what it is called but I think it's that manhwa where the FL insist that she didn't kill her husband and her multiple escapes from prison ( the ML was a war hero )
Yes that’s Your eternal lies!
It is actually same artist kkomak
Also drew
Charlotte's Letter
The Secret of the Lovely Duchess
Edit didn't draw Secret but story...
The art style looks so familiar…I can’t place my finger on it but I feel like there’s another story with this art style. The only one I can think of that looks similar would be Your Eternal Lies.
