When his granddaughter told him everything that happened in Yan Liguang's family due to the wrong marriage, Grandpa Yan's impression of Yan Liguang's family dropped to the freezing point.
If it weren't for Yan Yuling being his granddaughter's best friend, he wouldn't bother to investigate their family. But when he investigated, he discovered shocking information.
When he learned about Yan Liguang's family situation and Yan Yuling's childhood experience, he finally understood how Yan Liguang abused his daughter. Although he only wants to get the property of his first wife, Yan Yuling is his daughter.
How could he bear to let his mistress and that unknown man's daughter bully her like this? How could he love someone else's daughter more than his own?
Before, he couldn't understand why. But now that he thinks about the possibility that Yan Yuling may not be Yan Liguang's biological daughter, everything seems reasonable.
