Trusting only her talent in swordsmanship, Espin tried to become the best knight but failed. It was because of Duke Xenoc Blacknight, the no. 1 knight in the Empire. She hated him so much; he was nothing but an enemy."I won."She was finally able to beat him, but her last memory was leaving the chivalric order then jumping in front of a carriage to save a rabbit. She thought she was going to die just like that… but she got resurrected? She opened her eyes back in the Empire 18 years earlier, in a completely different body!"So if I gather sacred beasts like you, you’ll bring me back to my original time?"-Exactly!So if she helps the sacred beasts, she can go back to her original time and live a new life! Instead of being resurrected, she wanted to live and enjoy the things she wasn't able to before."No, I-I'm scared…!"The Xenoc from 18 years ago is crying while hugging her?!"You… said you would marry me. Why are you running away?"Will Espin, who suddenly became a time-traveler, be able to fulfil her mission and go back?---**Original Webtoon:** (https://webtoon.kakao.com/content/%EC%9D%B4%EB%B4%90%EC%9A%94-%EC%95%84%EA%B8%B0-%EA%B3%B5%EC%9E%91%EB%8B%98-%EB%88%84%EB%82%98%EB%A7%8C-%EB%AF%BF%EC%96%B4/2878), (https://page.kakao.com/home?seriesId=59457640)
