Phantom of the Floating City

In the floating city on the sea, the rich and powerful are intertwined, and the Yan family hides a secret that no one knows - two girls with similar looks share the identity of "the Yan family's legitimate daughter". The adopted daughter Yan Xi is gentle and self-possessed, playing in the family chess game in the name of her legitimate daughter, but always longing for her own destiny; the real daughter Yan Yin is frail and intelligent, and has been hidden in the back building for half her life, making plans and knowing the past and present, hiding in her heart her obsession with freedom and self. The boy next door, Lin Er, is sharp and transparent. He accidentally fell in love with "Yan Xi", but he was keenly aware of the mystery behind his identity. Little did he know that he had already crossed paths with the real Yan Yin when he was young. A diplomatic storm swept across the floating city, and the Yan family was in danger. The two "selves" finally broke through the wall and met each other. There was no fight, only mutual admiration and redemption. When their identities are misplaced and their fates are entangled, the three of them will uncover the truth hidden under the shipping hegemony and the secret struggle of the Seven Seas on this floating island, and rush towards their own redemption and rebirth.
