"Second Grandpa." Inside the Shen family's private plane, Shen Xinyue smiled, "He..."
"He is the legitimate son of the Shen family, without any doubt." Shen Motian interrupted Shen Xinyue's words calmly yet firmly.
Shen Xinyue's heart tightened. No one understood the weight of those words better than she did.
On the surface, the Shen family doesn't emphasize legitimacy because the concept is somewhat ambiguous; they generally only refer to internal and external family. As long as one is within the family circle in the Capital City, they are internal, while those stationed elsewhere are considered external. Even if Shen Mochen is the descendant of Third Grandpa Shen Moran, he would be internal, not a legitimate son.
Shen Xinyue is the daughter of Shen Wanhua, the second son of the current Family Head, Shen Muchong. However, even she wouldn't normally claim to be the Shen family's legitimate daughter—she just doesn't correct outsiders when they introduce her that way.
