Three years ago, Lin Zhiwei, a "genius girl in the jewelry industry," was framed by her boyfriend Gu Haochen and her best friend Su Manwen on the eve of her engagement. The core design "Stardust Trail" was tampered with as Gu Haochen's original work. Instead, she was accused of "attempted plagiarism and mental disorder." The studio left by her father was sealed, and her mother's old illness relapsed. She also "died socially" due to online violence and industry bans.
But Lin Zhiwei was not defeated. She stayed anonymous for 427 days and transformed into the mysterious designer "Echo": practicing ancient metalworking in an underground workshop in Florence, winning reputation with her advanced concepts in anonymous forums, and collecting time stamps, original manuscripts and other evidence with lawyer Xu Yunting to lay a revenge network.
Later, "Echo" was invited back to China to become Gu Haochen's "special consultant". He was his partner during the day and implemented his revenge plan at night. At the press conference on the 119th floor of Shanghai Tower, Lin Zhiwei first took off the mask to prove her identity, then released the evidence, and finally showed the "Light Trace" series, which ruined Gu and Su's reputation and restored her identity as the original creator.
At the end of the story, Lin Zhiwei used the compensation money to set up an "anti-plagiarism fund", restarted her father's studio and established "Echo Studio" with Xu Yunting. She said that "revenge is not the end, only making darkness unable to regenerate", conveying the belief that originality will eventually be recognized.
