"Severus lived near our house when he was a child. Lily and I knew him long before Hogwarts started."

"Wait, wait? Aunt Petunia!"

At this moment, Harry suddenly widened his eyes and looked at Aunt Petunia in shock.

"You just said that Professor Snape turned out to be your neighbor, so the professor and my mother actually..."

"Childhood sweethearts, or good friends. Didn't you know? They both enrolled in the same class."

Petunia Dursley shrugged and hesitated a few times, feeling a little uncomfortable with the suddenly focused eyes around her.

"I heard that the two of them had a big fight later. I don't know exactly what happened. Lily didn't mention him after that. I thought that the guy had an accident - but the relationship between them was really rough at first.

Okay, we play together almost every holiday."

"You...neighbors? Wait, Professor Snape is not a pure-blood wizard?"

Before anyone else could continue asking, Harry suddenly realized a problem and asked in surprise.

"I mean, aren't his parents both wizards?"

"No - he told Lily he was a half-blood wizard."

Aunt Petunia looked at Harry inexplicably, recalled the past memories, and spoke slowly with some difficulty.

"His mother is a witch, she seems to be named Prince or something. Old Snape should be an ordinary person here - but old Snape has a particularly bad character. He drinks alcohol, gambles, and often beats and scolds their mother and son.

It seems that the family moved away at some point later..."

Half-blood, Prince...Prince?!

Harry barely had any attention to listen to what Aunt Petunia said next.

At the same time, the signature on the title page of the old potions textbook appeared in his mind.

[This Book is the Property of the Half-Blood Prince]

At the same time, Hermione, who was originally a little helpless towards her father, seemed to have thought of the same problem. Her eyes wandered back and forth between Aunt Petunia and Harry in confusion. If there weren't so many parents, she would have wanted to read it now.

Looking through Harry's schoolbag.

Unlike Harry, Hermione only had one big, angry word left in her mind:

Cheating!
