One Day My Sister Died

My sister was sold off from the House of Pellièse, only to return as a corpse—dead after becoming the bride of the monstrous, dethroned prince. Now it’s my turn. I am to become his ninth bride, bound for the ominous black mansion where he waits. "And after the first night?" "Once we’ve spent it together, Your Highness, you won’t be able to cast me aside—even if you wanted to." In that dark mansion, where the man suspected of murdering my sister resides, I will survive. And I will uncover the truth behind her death. Whatever it takes. **Original Novel:** Chapters, Volumes **Original Webtoon:** Naver Webtoon, Naver Series Alternative Names: - 어느 날 언니가 죽었다 - Vào Ngày Mà Chị Gái Tôi Qua Đời - One Day My Sister Died - One day My Sister Died - One Day, My Sister Died
