The beginning is high-energy - the heroine is not stupid, she knows from the beginning that she is a substitute. But she agreed to get married for only one purpose: to use this identity to get close to the Lu family and avenge her father who was killed by the Lu family. On the surface, she acts as a submissive stand-in, but secretly uses her status as a top jewelry designer to gradually dismantle the Lu family's industrial foundation by participating in international competitions and making top connections. The male protagonist began to regret after her "sudden awakening" and began a long journey to chase his wife. The sweet and sad thing is that every time she softens her heart, she will see the final letter left by her father, and then become more cruel.
