Hogwarts: I'm taking my dad to find my mom.

Harry was standing on the grass near the Black Lake, chanting Professor Lupin's Patronus Charm over and over again.

This is because, Lupin said, his father's Patronus was a stag.

What Harry wanted more was to find what his parents left in him.

"Expecto Patronus!" Harry raised his wand and shouted towards a certain place, but no matter how hard he practiced, he couldn't summon his own Patronus.

"Professor, I still can't do it."

Harry said to Lupin dejectedly.

Lupin touched his head and said, "Harry, you know, the reason I have always been reluctant to let you face the Boggart is because I am afraid that you will recall some bad memories."

"A Boggart, capable of instantly transforming into whatever we fear most."

"Of course, if you see something you are afraid of, it may increase your belief in protection."

Harry's eyes lit up, "Professor, are you willing to let me face that Boggart?"

"Harry, are you really ready?"

Lupin and Harry looked at each other, and Fang, who was not far away, saw Harry and rushed towards him.

He panted to Harry's feet and squatted down.

"Fang?" Harry touched Fang's fur and then found Agas standing on Fang's head.

"Little guy, what animal are you?" Harry stretched out his hand to touch Agas, but he dodged it.

"I saw him in Snape's office."

Lupin noticed the sparse feathers on Argas' body. "This guy was standing on Snape's shoulder."

"Snape's pet?"

Lupin frowned and thought, then shook his head subconsciously.

How could Snape have a pet? He couldn't even take care of himself and was looking sloppy every day.

"Woof woof!" Fang rubbed his nose against Harry's trouser leg, then bit the corner of his trousers, trying to take him back to Hagrid's hut.

But Harry didn't understand what he meant, and squatted down to free his pants from Fang's mouth.

"Ya Ya, go play by yourself. I'll play with you when I have time."

Fang sneezed and nudged Harry persistently.

"YaYa! He said he doesn't have time!" The considerate Agas cried into YaYa's ear.

Harry stared at Agas, "Strange, why do I feel like I've seen you somewhere before?"

Agas responded.

Then it flew from Fang's body to Harry's messy hair.

"Let's go, Harry."

Lupin patted Harry on the shoulder and took him back to his office.

After entering Lupin's office, Agas started flying around.

From time to time, comment on the decoration of Lupin's office.

"So poor!" He stopped on top of Lupin's shabby suitcase.

"Ragged!" He looked at Lupin's patched robe hanging on the hanger.

Finally, he flew onto Lupin.

“Stinky.”

Agas smelled a strange odor on Lupin, which made him extremely uncomfortable.

That was the smell of a werewolf, a smell of lush hair and strong body odor.

Fortunately, Lupin and Harry didn't understand what Agarth meant.

The two just thought that the bird was just wandering around and then landed on Lupin.

"OK! Harry, are you ready?"

Lupin patted the large box in the office.

Harry swallowed, then raised his wand in the direction of the box, "I'm ready."

Lupin forced the box open and a cloud of black mist rose from it, aiming at Harry.

The next second, the black fog turned into a dark small room in front of them.

There was only a slit of light coming through the small room.

The room was quiet and silent.

It was like a corner forgotten by the world, without any sound.

After seeing this familiar environment, Harry's breathing gradually became rapid, and his right hand holding the wand trembled.

"Expecto! Expecto!" He never finished his words, but just repeated the word Expecto.

Seeing that Harry's face was getting paler, Lupin put the Boggart back into the box.

"Are you ok?"

Harry sat on the ground, sweating, and nodded slightly.

"Harry, I thought you were afraid of the Dark Lord." Lupin sat down next to Harry. "Eat some chocolate, you'll feel much better."

"Why would I be afraid of him?" Harry shook his head. He was not afraid of someone who could be killed easily by him.

"So, what is that?" Lupin said to the box.

He was asking why Harry would be afraid of a dark room.

Harry was silent for a moment.

"my room."

“A cupboard space under the stairs, the light you can see is the world outside the stairs.”

"Petunia is my aunt, but she doesn't like me."

"Even the wizarding world and the death of my parents, I only heard about it from other people."

"My aunt and her family went on a trip and locked me in the house. When I was sick, I stayed alone in the room for two days."

"My aunt and her family don't care whether I live or die."

“That room is where I feel most at ease, but it’s also where I’m most afraid.”

"Because no one knows how suffocating it is in there except me."

Harry became more and more agitated as he spoke. He couldn't understand why Petunia hated him so much when his mother and she were sisters.

"If I hadn't begged them to give me an electric light, my room would have been like a horrible world swallowed by darkness at night."

Lupin had never heard Harry say these things, and neither had Sirius, who took Harry home to live with him.

"Harry, you have to know that no one can please everyone."

Lupin took out some candies from his pocket and said, "Eat something sweet, you'll feel much better."

Harry restrained the expression on his face, suppressed his worries in his heart, looked at Lupin and said, "Professor, let's do it again."

Argas flew from Lupin's shoulder to Harry's head.

He just felt the resentment of the little boy.

Lupin glanced at Agas, stretched out his hand and said, "Come over here, little guy. The Boggarts won't be fun in a while."

Agas turned his head and his butt towards Lupin, rejecting him.

"Okay then." Lupin withdrew his hand. A small bird wouldn't do much for a Boggart. "Harry, I'm going to open it."

Harry nodded, looking determinedly at the opened box.

Agas, who had been standing to the side and had not carefully seen what came out of the box, also faced the box and stared at it intently.
