I'm not sure you've read this. It's also a good one, strong fl and strong plot. The plot is SUPER DUPER GOOD. Due to communication gap and misunderstanding between husband and wife, they both died miserably then the mc make her last wish that if there's a second chance she'll change their fate and start her second life. And the art styles and dresses are like Hourglass since both are produced from Ant Studio so always a best quality one but I think this one's art style is a little more beautiful than hourglass.

This's also a good one about fl changed into a strong character in order to protect her love one in second life
Any stories like The Villainess Reverses the Hourglass or concentration of malice?
