Ma'am Your Offspring is 4 and a Half Now

Five years ago, she left behind an egg, saying, "This is our son. When he grows up, I'll return to your side."

He thought she was pulling a joke, but several months later, the egg hatched. The boy looked in every way like a normal baby, except for the two tiny sparkling dragon horns on his head. The mother, on the other hand, did not fulfill her promise to return. In those five years she was missing, he almost went mad with grief, until the day his son brought home a woman. "Papa, you may not have a wife, but you'll have a daughter-in-law soon! This lady saved me, and I'm going to marry her!" the boy said. From then on, the father and son engaged in a fierce competition for the woman’s affection.
