The Heir's Exclusive Remedy

To avoid being given to a perverted old marquis by her clan, Su He, the Su family’s legitimate daughter, schemed to stay with Crown Prince Pei Yan as his "antidote". Their toxic relationship of mutual use turned to love amid noble infighting and life crises. With her mother’s otherworldly wisdom (cooking, business), Su He sought independence, while Pei Yan suffered a deadly poison and court conspiracies. When Su He’s identity and the poison’s truth tied to a treason plot, they teamed up to defeat the Lu and Su clans. Pei Yan gave up his power to protect her, and amid fireworks, he promised her a lifelong love. Su He, free from shackles with her own career, walked with him to forever.
