“Who are you?” — Fenrir, the emperor notorious for his cold-heartedness, points his blade at Aria.

Wait, isn't this the wedding night scene from the beginning of the story where she's killed off effortlessly?!

The memories of this shocking scene belong to a novel she had read in the past. — Am I really that Aria?

Within the flood of memories, she sees her past: abused because of her "loathsome black hair," treated with a world of difference compared to her sister. She was like a doll with its heart locked away.

“If I die just like this, it’s too pitiful for both Aria and me!”

Shaking off a past steeped in malice and bravely facing forward, her earnest spirit lights a fire in the "Coldhearted Emperor's" frozen heart.

This is the story of the "Substitute Bride" who thaws the heart of the lonely king—a woman who was never meant to be loved, finally finding true love.
