Intending to save her life and run away, she lies that she is his older brother's ex-girlfriend! However, the lie is exposed on the spot by the rightful master, the older brother Bo Xun. Wanting to stay away from the hustle and bustle, she instead spends her days and nights with the amnesiac second young master Bo Si. With the older brother Bo Xun acting as the intelligence anchor and overseeing things, as the lies are peeled back layer by layer, she breaks free from the fake identity, rewrites the original work's tragic ending, and generates heart-fluttering signals.
