"Six years ago, a tragic accident took away Sai Lin’s most precious memories. She forgot the girl who once captured her heart, but the feeling of searching for that person never disappeared.
Years later, the cold and powerful CEO Sai Lin signs a contract with an ordinary girl, Ai Wei, asking her to become the replacement for her lost love. Ai Wei believes she is nothing more than a shadow of someone else—a substitute created to fill an empty space in Sai Lin’s heart.
But as they spend more time together, Sai Lin begins to realize something she cannot explain. She remembers Ai Wei’s little habits, worries about every injury she suffers, and even without her memories, her heart still chooses to protect her.
When an old Polaroid photo reveals the hidden truth, Ai Wei discovers that the person Sai Lin searched for all these years was never someone else.
It was always her.
Now, they must face the pain of lost memories and unfinished love to finally find their way back to each other.
She was never a replacement. She was never a forgotten love. She was always the one."
