Synopsis: Gouman Reijou wa Chi no Keiyaku de Ai o Shiru

Silwyn Rigwon, the youngest daughter of a frontier marquis, believes in her own beauty and worth more than anyone else. At eighteen, she still has no fiancé, not because she lacks appeal, but because of her excessively high standards and self-love. However, by royal decree, she is forced into marriage with her first love, Aster Dilseon. Yet when they reunite, Aster is nothing like the man she once knew. He has become cold and cruel… and worse still, he keeps his lover within his estate. Scorned not only by her husband but also by the servants, Silwyn lives each day without a place where she belongs. Determined to reclaim her trampled pride, she resolves to take revenge on Aster. The target of her plan is his “lover,” Aura. Silwyn quickly sees through the truth: Aura is actually a man disguised as a woman. Using his secret as leverage, she orders him to cooperate in her revenge. As they work together and gradually touch upon each other’s true feelings, their relationship—once nothing more than a partnership of convenience— begins to transform into something special. Then, Silwyn is pushed to the brink of death. To save her, Aura sinks his fangs into her neck—sealing a vampire’s contract that binds their lives together as one. A romance fantasy where an arrogant noble lady and a vampire pretending to be a lover for his own purposes are bound by a blood pact. [Original Webtoon](https://www.comico.jp/comic/11492)
