He is Ye Chen, a man standing at the top of the wealth pyramid, but he hides a secret that no one knows - there is another completely different personality dormant in his body. She is Su Ning. On the surface, she is the unpopular daughter of the Su Group. She is struggling under the cold eyes of the old lady and the calculations of her cousin Su Jiaojiao. However, her true identity is the eldest lady of the ancient Windsor family in Europe. She is backed by her powerful brother.
In a well-planned frame-up, Su Jiaojiao's medicine made Su Ning unable to control herself; after an accidental attack, Ye Chen also fell prey to the medicine's properties. By mistake, the two broke into the same room, and on the edge of confusion, they became each other's only antidote.
When the cold Ye Chen meets the forbearing Su Ning, when the gentle sub-personality breaks through her disguise, love and hate breed in the pull of the dual personalities. Her secret identity, his split soul, together with the family conspiracy and past grudges, entangle the fate of the two. Is it the redemption of sweet pets, or the abyss of sadomasochism? This entanglement that started out of an accident will eventually reveal all disguises, letting the truth and love sink together.
