Unexpectedly, not only did she get caught red handed, she’s also pregnant with child before marriage.

In the end, the baby she carried for ten months turned out to be a little fox, and it could cry “Mama” once born? Fortunately for her, the child is well-behaved, kind, and caringly protective of his mother.

In this world filled with both evil and good, this pair of mother and son will work together to destroy all their adversaries. As for the scumbag relatives who scorned them, they will make them pay dearly with regret in mind.

But then one day, baby fox’s father suddenly showed up, not only to steal the child, but to steal her too? How can there be such a good thing? This foolish father of his, didn’t even ask for little fox’s opinion?
