余命七日の聖女~身代わりの花嫁は封印へ~

Scarlett, an elven saintess, distrusts love due to her mother's fate. Moved by Carlos, she agrees to marry him, but before the wedding, she discovers a plot: she is merely a scapegoat to deflect a curse, and his true love is the noble elf Raven. Heartbroken, she volunteers to guard an ancient seal. Over a seven-day countdown, she gives Carlos chance after chance, yet he always chooses Raven. Finally, she sacrifices herself to hold the seal. Carlos is devastated—but too late.
