Qi'an Puzzle

When Shen Weiyang was desperate, she accepted a devil's deal: to impersonate Song Qingci, the fiancée of Lu Jinshen, the leader of the Lu family, who "missed" due to an accident, for a period of one year. Lu Jinshen's memory was blurred due to a head injury, and he could only remember the outline of his fiancée. Shen Weiyang successfully moved into the top-notch mansion called "Qi'an" by virtue of her 70% similar appearance and carefully trained demeanor. During the day, she was an elegant and gentle Mrs. Lu, learning flower arranging, French, and dealing with temptations from celebrities; at night, she hid in the deepest corner of the cloakroom, reciting Su Jianyue's diary to the bug, trying to act like a woman she had never seen before. She acted with all her heart, but often when she came back from her dreams at midnight, she would meet Lu Jin's sober and heart-stopping eyes. Sometimes he was gentle and affectionate, calling her "Yue'er"; sometimes he seemed to be gazing at someone else through her, his eyes like ice blades. Until a certain charity dinner, a woman with the same face as Su Jianyue made a stunning appearance and took the hand of Lu's sworn enemy. The whole place was in an uproar, and all eyes were focused on Shen Weiyang. That night, it rained heavily in Qi'an Manor. Lu Jinshen trapped Shen Weiyang in the collection room, his fingertips brushed the corners of her trembling lips, and his voice was as low as a lover whispering: "Tell me, my real 'fiancée', now it's time to deal with the fake one outside..." "Or is this more charming liar beside me?" ——Your stolen identity is fake, but my heart for you is real.
