On a cold, rainy night, Su Wan saves a man covered in blood, acting without a second thought. She only wants to escape the suffocating cage of her family, unaware that one glance has roused a dormant beast.
He is Lu Chenyuan, an absolute ruler whose name makes both the underworld and the respectable world tremble, wielding power over all and a heart of ice. Her arrival is like a faint yet stubborn light shining into his unfathomable dark empire. The fading scar on her wrist, in particular, tears through time and awakens memories long buried. It turns out that when he was young, lonely, and on the brink of despair, she had already become the salvation he could never forget.
This time, he will never let her go again. Using force and plotting at every turn, he weaves an exquisite cage in the name of love, vowing to keep her forever beneath his wing as a treasure belonging to him alone.
Su Wan refuses to be a canary with clipped wings. She struggles and flees time and again, yet finds herself moved and drawn in by his obsessive, passionate love and the tenderness he lets slip without meaning to. Family power struggles, career upheavals, the protection of a childhood friend, and the turmoil stirred by his unattainable first love: one trial after another comes their way.
When the undercurrents finally subside and the schemes fade away, they will come to understand that love is not possession or control, but saving each other and growing together. See how this romance, which began with coercion, finds its way to a happy ending, until everyone discovers their own happiness at the end of the story.
