I can't remember the name but I vaguely remember the plot. This illegitimate FL with red hair is forced to take the place of her half sister who's getting married to this war hero ML who the illegitimate FL saved when he was a kid. The ML doesn't recognize the FL at first but slowly starts to figure out she's the one who saved him. The half sister gets jealous of the attention the FL gets from the ML and decides to marry the ML herself but gets blown up.
