Mainly some daily stories, more light-hearted. It has nothing to do with the original plot.
Here is the introduction:
Narcissa Malfoy and Fia Grint have been close friends since childhood. The two married one after another and gave birth to Draco and Loya in the same year.
In 1980, Loya was born in St. Mungo's Hospital. The first thing she saw when she opened her eyes was Draco on the hand of Aunt Narcissa.
In 1991, 11-year-old Loya received a letter from Hogwarts. On the express train, Draco sat next to her who was as excited as she was.
They grew up together, spent a memorable childhood together in Malfoy Manor, rode broomsticks secretly, plucked the white peacock's feathers together, learned to refine potions together, and were punished together... These small daily life led them to grow... Experience... And finally grew together to become outstanding graduates of Hogwarts - an excellent wizard.
