[HP] What Do You Mean I Bumped Heads with Potter's Godfather?

Many years later in the Auror office, when Nicholas Demetrius faced Harry Potter who had become the director at a young age, he would still think of the afternoon when he was dragged to the corner of the library by this man. At that time, Harry Potter, a boy who was nearly a year and a half younger than him, could still be considered skinny and a head shorter than himself, placed a photo album in front of him, pointed at the black-haired man who was exactly like him, and asked himself if he knew who he was. Nick remembers his response: "—He looked so happy, I wish he was my dad." But news of the murderer followed one after another, and catastrophic days swept through his aloof fourth-year life at Hogwarts. The main culprit came from the "Boy Who Lived" himself - the green-eyed Harry Potter. In fact, it didn't take long for Potter to figure out the whole story in the summer. And it seems that the savior's way of apologizing is very fresh and refined. "Can I kiss you?" Nick: ... But it's really weird, you know? - Things to know before visiting: 1. Nick is a Slytherin. This guy is a bit bad! 2. Only Harry's part of the original romantic relationship has been modified, and the main CP is Harry × the original man. 3. Contains original families and characters. There will inevitably be bugs and inconsistent logic, so please forgive me. 4. This article tries its best to shape the characters according to the original character settings. If there are any OOC, I will be the first to kneel down, but don't talk too much about the original characters. 5. No one is perfect. This article may not be suitable for those who pursue a perfect protagonist. 6. The storyline will unfold from Nick's origin story. In addition, the story narration will follow the rhythm of the original work. I want to show the perspective of non-original characters facing Harry's storyline, but because JJ prohibits copying the original work, there will be magical modifications and original designs. 7. A love line will be obviously introduced after Harry's third year. Nick is a year ahead of Harry. 8. The pace is slow, the foreshadowing is long, and there are many private settings. 9. I may be seen parodying the language style of the original work, and stuffing in a lot of weird little cleverness. 10. If there is a source of inspiration, it will be marked at the end of the chapter and some thoughts will be given (?) Purpose: Understand each other and grow together
