Harry woke up from his bed in the hospital wing and saw the white ceiling.

"Here you go, Harry." He heard Hermione's voice and reached out to take it - it was his glasses.

After Harry put on the glasses, his vision became clear and he saw Hermione and Ron sitting beside him. Madam Pomfrey was mixing potions on the small table beside the bed, and Professor Lupin was leaning over to check on his condition.

Across the aisle, Professor Happ was sitting leisurely on the bed opposite, flipping through a copy of the Daily Prophet.

"Professor--"

"Kid, drink it first." Madam Pomfrey said. Harry struggled and said, "I think I'm fine!"

"Oh, really?" She said absent-mindedly, "That doesn't stop you from drinking up the potion. Hurry up, or I'll change it to a potion of life and death."

Harry drank up the liquid in the cup in one breath. He looked at Felix and said anxiously, "Professor Hep, did I last two minutes?"

Felix put down the newspaper, smiled and said, "Your last move was pretty good. I was planning to time it."

It was not until two or three seconds later that Harry understood what the professor meant. He showed a surprised expression, "So, I, I..."

"Well," Felix winked at him, "You can take your time to consider the wish. Don't make it too difficult, otherwise I will refuse."

Harry blurted out, "I want to know about my father, and Sirius Black!" He glanced at Professor Lupin next to him - he was looking at him in astonishment, so he whispered, "Thank you for coming to see me, Professor Lupin."

Professor Lupin said gently, "It's nothing, I just happen to be free tonight. Harry, about your father--"

Madam Pomfrey brought a blanket, "It's a bit cold at night, cover yourself with this." She turned her head to look at the two professors, and said impatiently, "The patient needs to rest, so try to be brief."

Professor Lupin changed his words, "Harry, I know you have some questions. You can come to me this weekend. I won't bother you for now, Professor Hep, shall we talk together?"

Felix stood up, "Of course."

The two walked out of the office together, and when they turned a corridor, Lupin stopped, "Professor Hep, we need to talk."

"About Potter?"

"Yes, about Harry." Lupin said calmly, "It can be seen that you treat him differently. But don't you think that some of your practices are not suitable for a third-grade child?"

"What do you mean?" Felix looked at him curiously.

"Summer special training, please excuse me, they were in the same compartment with me at the time, and I heard some of it. From Harry's description, he fainted more than a dozen times during your special training..."

Felix said casually, "Maybe more than that, if the data I recorded is correct, it should be 32 times."

Lupin looked at him seriously, "Don't you realize the seriousness of the problem? He is only thirteen years old!"

"What does age mean? Will Black let him go just because he is young and wait until he grows up before taking action?" Felix said with a sneer, "If you are worried about his health, there is no need to. I am fully prepared."

Lupin suppressed the anger in his heart, "Harry will be safe in school. Besides, not everything can be explained away by 'being prepared'. Have you considered his psychological endurance? What were you doing when you were thirteen?"

Felix looked at him expressionlessly and said softly, "In my opinion, your reasons are all excuses. At least, I won't pin my hopes on others and pretend that nothing happened."

Lupin calmed down, hesitated and said, "I don't want my words to show any prejudice, but you are from Slytherin and you are Snape's student..."

"What do you want to say, Lupin?" Felix knocked on the window frame in front of him. "I'm in a hurry."

Lupin took a deep breath. "I care about Harry's safety more than anyone else, and you have a huge influence on him. Snape and his father were sworn enemies when they were in school, and I'm worried that Snape's attitude will affect you."

Felix looked out the window. "Severus can't control me, but I really don't intend to change my teaching philosophy. Professor Lupin, you are too nosy. What does Harry have to do with you? Let's part ways here."

He took a few steps and counted silently in his heart, one, two, three...

"I know Harry's father! We are good friends, even far beyond the limitations of this vocabulary, and I am very grateful to him." Lupin said suddenly.

Felix, who had his back to him, raised the corner of his mouth. He looked back at Lupin, "You expect to convince me with vague words?" "

...Harry's father, James Potter, he is a genius in the school, he can learn anything quickly, he is a top figure, and Sirius... I mean Black." Lupin stood side by side with him, looking out the window, the sky had completely darkened. "I was a marginal figure at the time, and it was James who accepted me."

"James and that man were young and energetic, with flamboyant personalities, very popular among classmates, and James later joined the Quidditch team. But on the other hand, they also became targets of Slytherin."

Felix asked with interest, "Can you tell me more?"

Lupin thought for a moment and carefully chose his words, "Slytherin at that time... may be different from what you have come into contact with. The theory of the mysterious man was very popular, and many students joined the ranks of Death Eaters as soon as they graduated. We privately called them Death Eater reserves."

Felix nodded and said, "I did hear about it."

"James and that man was Sirius Black. He was a good man at the time." Lupin said with difficulty, "They soon became a banner of Gryffindor. James was carefree and liked to play pranks, but he hated evil and always protected his classmates in the academy. As for Black, he strongly disliked the corrupt family he came from, and he also had no good feelings for Slytherin. He even broke off relations with his family at the age of 16. I just didn't expect that he would betray James in the end." He shook his head and didn't continue.

Felix had already understood what he had not expressed, and he said with emotion: "How can we not feel sad that a young man full of justice turned into a dragon?"

Lupin continued: "James and Black offended a lot of people. Of course, some people did hate them because of their pranks, but they didn't care about it. Peter and I also participated in it. Looking back now, I always feel incredible about my stupidity at that time."

"Are you not just telling me about some experiences in your youth?"

"I'm almost there. James and Black had an old enemy at the time, the current Potions Professor, Severus Snape. They fought openly and secretly, and for some reasons, this fight even reached a climax in the last few years."

"Because of Harry's mother?" Felix interrupted him and asked. From the information he had found out, it seemed that it was mostly about emotional entanglements. "Excuse me, I found out some information privately."

Lupin stared at him with a complicated expression, and said after a while: "You are really an out-and-out Slytherin, Professor Happ. I don't mean to belittle you, but you obviously know some inside information but you keep silent..."

Felix said briefly: "I know a little bit, and I can't get a glimpse of the whole picture of the year, but it can still be used to distinguish some doubts. Please continue, Professor Lupin..."

Lupin said speechlessly: "It's far more complicated than that. I am one of the people who know best, Professor Happ, I hope our conversation will not be leaked."

"At least I won't tell it." His eyes swept across the corner of the corridor and showed a playful smile.

But what if someone is here?

"Harry's mother, Lily Evans, was good friends with Snape before they entered the school, and James and Black hit it off right away. It was a strange fate that made them sit in the same carriage in their first year, but the meeting was not pleasant. After entering the school, James complained to Lily and reminded her that she should not make friends with Slytherin people, they were all a bunch of scum, but Lily ignored him."

"It didn't take long for me to become friends with James and the others, and I brought Peter along. The four of us were inseparable, a bit like Harry and his two best friends." He smiled and said that it should be the best memory of his life.

"As I said before, James and Black quickly emerged and gained a large number of fans. As for their relationship with Snape, it can only be said that it is somewhat similar to the current Harry and Malfoy. Snape has too many things that James doesn't like: he is unkempt, studies the dark arts, is a Slytherin, and also pesters his classmates."

"Why pester? I remember you said that Snape and Harry's mother were good friends." Felix asked.

"That's right, but you can't expect a little boy of eleven or twelve to analyze the problem calmly, not to mention that James and Sirius..." He paused, "They both have impulsive personalities."

"The conflict between James and Snape escalated quickly. James cursed Snape, and Snape developed various spells to fight back. Lily always defended Snape and disliked James in various ways."

"Several years passed like this, and James' heart began to move," he smiled, "He suddenly had a good impression of Lily, who had always been at odds with him, and tried to strike up a conversation with her, but how could Lily pay attention to him? James quickly changed himself. He became less arrogant, and didn't always show off. In short,

he showed a mature side..." "His fight with Snape was also moved to the dark, so that Lily couldn't see it. We didn't think it was wrong. At that time, Snape had already shown a strong talent for potions, and was deeply loved by Professor Slughorn, who gave him a lot of special training. We all agreed that if he graduated, the Death Eaters would definitely become stronger."

"In the meantime, because of some pretty bad things, Lily and Snape broke off their friendship, and James took advantage of the situation. Please forgive me for using this word, but the meaning is similar."

"James and Lily got together, and his relationship with Snape became more complicated - personality differences, ideological disputes, and finally emotional problems."

"If you ask me, the person Snape hated the most was James, and the second might be Black. It was he who acted as an undercover agent for the mysterious man and leaked the address of Harry's family. Oh my God, I don't know how to tell Harry that James trusted him so much and made him Harry's godfather..." Lupin said with red eyes.

"Professor Happ," Lupin looked at him and said sincerely, "We haven't met much, but I can see that you are a serious and responsible professor. Some of my students like you very much, even though they are not old enough to take your elective class."

"I told you these past events in the hope that you will not be influenced by Snape. Please believe me, my feelings for Harry are sincere."

Felix was silent for a moment, "Professor Lupin, you think too much. Harry is a student I am optimistic about, and I am also looking forward to his future." Lupin

left, and Felix looked at the corner, sighed softly, and left from the other side.

At the corner of the corridor, Harry sat silently on the ground, and Ron and Hermione looked at him with complicated expressions.
