On impulse, she sends him a letter, begging him to become her guardian. At that very moment, after a heated quarrel with his father over his sister’s marriage, Trish leaves the ducal estate and heads without hesitation to the Winter Conservatory in the domain of Redian, where Emblin awaits. “I, Trish Eicke, swear before God and pledge my honor as witness, that I shall protect Emblin from this moment on until death breaks my vow.” Original Novel: <a href="https://series.naver.com/novel/detail.series?productNo=5864981" target="_blank" rel="noopener noreferrer">Chapters</a>, <a href="https://series.naver.com/novel/detail.series?productNo=6597494" target="_blank" rel="noopener noreferrer">Volumes</a> Original Webtoon: <a href="https://comic.naver.com/webtoon/list?titleId=843948" target="_blank" rel="noopener noreferrer">Naver Webtoon</a>, <a href="https://series.naver.com/comic/detail.series?productNo=13248652" target="_blank" rel="noopener noreferrer">Naver Series</a>
