Xiao Xiao, an ordinary office worker in the 21st century.

She transmigrated into a novel with multiple identities, becoming the female lead's adopted younger sister, a cannon fodder character who was always causing trouble.

Their fate was extremely tragic; they were basically killed without a complete corpse.

Fortunately, her timing was perfect; it was the day before the original owner caused trouble for the first time.

She felt that God had been kind to her; at least she hadn't started her life in a terrible way. Thank goodness.

However, just when she finally managed to latch onto the female lead and was ready to live a life of luxury with her, things took a turn for the worse.

Her biological parents found her, and the truth about her transmigrating into the book came to light.

Qin Yan: "Hello! Let's get to know each other again. I'm your fiancé."

(P.S.: The female lead is a character who grows and matures; she's initially a cute and innocent girl. Also, for plot purposes, the older sister has a slightly larger role in the early stages, so please be gentle if you mind.)
