Yan Qingsi is too Vicious; She is Not a Nice Lady

"Then her father went to the city and managed to entice the daughter of the Ye family. He abandoned her mother and drove her to her death. Yan Qingsi was adopted into the Yans when she was eight, and it was publicly announced that her mother was the mistress. Yan Qingsi has thus always harbored a grudge in her heart and sought to avenge her mother when she got older. Her methods are…vicious, but she has never done anything to harm Meimei and Tingfeng till now. In fact, she protected Meimei plenty of times before."

 The eldest son was worried about his sister, so the first thing he did after hearing about this Yan Qingsi was to investigate her.

 When Grandpa Su heard about this, he released a sigh. Usually, when filtering through potential sons- and daughters-in-law in their family, they did not require them to come from an affluent background, so long as their background was clear. Their personality was more important.
