Okay all I remember is that the female lead reincarnates into this book from modern Society and she uses her modern knowledge to help her fate because the saint is actually reincarnated to from modern society and is confused why the female lead changed so much so she starts to resent her she also steals her man and tries to win up the fl in everything even trying to introduce the concept of iPhones without even knowing how to make one so she looked like a fool. The Saint try to make the male lead impressed by making spicy Korean food, but which was too much for the people at the time, but then the female steps up and uses her knowledge to make some sort of dumplings with a spicy sauce, which everyone loves the other girl suspect that she is the same as her.
I think it is The Villainess Reverses the Hourglass because I've been reading it and it sounds like it. But its not a webtoon so I'm not sure if I'm right. 2 reply
