Jewelry executive Di Shuang suffers from a special form of prosopagnosia, being able to clear only the face of bar worker Lan He. An accidental encounter brings them together, and Di Shuang, attracted by Lan He's outstanding appearance, wants to keep him by her side, little knowing that beneath his layers of hidden identities lies an astonishing status. Lan He is actually the secret crown prince of the Pei family in the capital, who fell in love at first sight with Di Shuang ten years ago and has been silently guarding her by her side. The two gradually develop feelings amidst ambiguous tug-of-war and misunderstandings and testing. As the layers of hidden identities peel off, the old case of the orphanage fire and the conspiracies of the Huo and Lan families gradually surface. The two join hands to fight against the behind-the-scenes enemies, uncover the mystery of their lineage, and finally rush towards each other to reap a complete romance.
