Well, it won't happen in this lifetime! Longyue thought.
She was the mastermind of everything now!
She had specially embroidered those two handkerchiefs with special poems for that shrew and Pei Jinheng!
She knew that Pang Shuangyue, who was far away in the capital, had been thinking about her!
Pang Shuangyue also liked Pei Jinheng. In order to have him, she first set Longyue up to make it look as though she was having an affair with another man to Pei Jinheng. In a fit of anger, Pei Jinheng broke off the engagement. Then Pang Shuangyue pretended to atone for Longyue's sins by marrying into the Pei family.
However, Longyue realized that Pei Jinheng still had some feelings for her, so she carefully set up this scheme.
At that time, the incident was also triggered by an embroidered handkerchief, but that handkerchief was not embroidered by Longyue. Instead, it was made to imitate her previous embroidery work.
