Zhou Huaijin rarely got off the wagon with her before.
For one thing, Yan did not have the intention of revealing her relationship before she entered Saint College, and for another, she did not want the Gu Mansion to use him as a supporter so that they could commit terrible things. However, now Yan managed to enter Saint College smoothly and Lord Ling insisted on marrying her half sister, so Zhou Huaijin was worried that Gu Zhenkang would treat Yan terribly, since he was not aware of what happened.
Although Sword One could keep Yan safe he still did not want Yan to be sad over some matters. At least with him around, the Gu Family would think twice before they did something.
The guards of the Gu Mansion all got frightened at the sight of Zhou Huaijin. They kneeled down and greeted him instantly.
Seeing the scene, Gu Chaoyan smiled at him. "Here I am, just go home and do your own business."
Zhou Huaijin nodded. "I will see you."
