The Thorn and the RoseEpisode 3

In order to save her mother, Vivian was forced to take her sister's place and marry the rumored cruel and bloodthirsty heir Alex. She accidentally discovered that she was the only "antidote" that could soothe his madness, and with her extraordinary mind, she changed from a "victim" to an indispensable "weapon" for him. Amid numerous conspiracies inside and outside the family, the two team up to fight against a common enemy and uncover a bloodline curse that spans a century. In the end, Vivian awakened the true power of the guardian, transformed from the "antidote" to a queen who stood side by side with the tyrant, and jointly took charge of the huge business empire.
