In modern urban society, Lilian flees an arranged marriage forced by her strict father. In a frantic street escape, she impulsively kisses a stranger named Silas. To her shock, she later discovers he is the son of her mother’s fiancé. Forced to live under the same roof as fake siblings, the two struggle to resist their intense, irresistible attraction to each other.
On the surface, Silas appears casual and unrestrained, yet he secretly guards Lilian in silence. He stands against her oppressive father, helps her restore art paintings, and spares no effort to safeguard her artistic dreams. However, their relationship is repeatedly blocked by overwhelming family pressure, complicated stepfamily ties, threats from business rivals, and the forbidden taboo of their fake sibling identity.
As engagement conspiracies, hidden camera blackmail, and violent conflicts break out one after another, Silas finally drops his playful disguise. He firmly chooses to stand side by side with Lilian, bravely confronting the suppression and prejudice from both powerful families to fight for their hard-won love.
