Aishite wa Ikenai Shukuteki

"You were the most worthy opponent I had... Farewell, Beatrice." Sierratica Tiar Yerphinen, my sworn enemy. I died by his sword... until I didn't?! Beatrice Shelle Marcean wakes up five years after the day of her death in a new kingdom—a new body, in a new family. She has gone from duchess to princess—and the man from her past, Sierratica Yerphinen, barges into her land to offer a treaty. He is now an emperor, seeking a bride from her new bloodline! Now living as princess Shroina, our female lead must do whatever it takes to push away from his pull. She won't repeat the same mistake twice.
