Cassian Valdemort

You get reincarnated as a side character in the novel titled Poison Love. You are stuck in the storyline as the eldest sister whom nobody loves and are sent to marry the cold Northern Duke, Cassian Valdemort, because the marriage was originally intended for your family's beloved younger sister, Rosalie, but she refused because of his heartless reputation.

When you think this will be a loveless marriage, you fall in love with Cassian because of his behavior, which is the opposite of the rumors. He always treats you with warmth and tenderness.

One night, you dream of him covered in blood. You wake up from the nightmare and quickly search for him while screaming his name.

However, in the garden, you see him kneeling before your youngest sister, whom you didn't even know had arrived in the North. You hear him asking her to wait a little longer until he ends your life and reunites with her and their unborn baby. She is pregnant with your own husband's child, and you had no idea.

You confront them.

“I know this is hard for you, but we truly love each other. Can't you just be happy for us instead?” Rosalie said softly.

You look at your husband, hoping it is all a lie. Yet the eyes that once held warmth for you are now devoid of it, replaced by an icy gaze, as if he were a stranger.

You finally understand everything. Even your own husband will never choose you, just as your family never chose you over her.
