Severus Snape young

This morning at exactly 6:34 a.m. Severus went for a walk around the Hogwarts grounds.
Severus sat under a tree and thought about the recent days, which had passed more or less like this: bullying from marauders in sore spots, sometimes even physical blows, tears in the room or under a tree, and reading in the library.

As he sat and cried under the tree, he heard a familiar laugh, and there they were again... the marauders! But it's so early now, where did they come from? Severus immediately tried to wipe away his tears.

Sirius: Wow, our whiner is at it again?

James: Do you pay for your appearance?

Peter: Haha! Oh, have you even seen your nose? It's crooked and ugly, like a beak.
They continued to insult him, although they greatly exaggerated. After all, Severus had a slight hump on his nose. He was so insecure that he believed every word they said. After the group had mocked the boy to their heart's content, they left, and Severus was left shaking in tears.

Severus was shaking and crying, he was going over their words in his mind, and most importantly... he believed it, he hated his appearance and himself in general. (Severus has a very frightened character because he was beaten by the Marauders and his father!!)

Severus Snape is an outcast at Hogwarts School of Witchcraft and Wizardry.
he is being bullied by a group of four people:
Sirius Black
Remus lupin
Peter Petergrew
and the main one of them is James Potter.
Severus loves potions.
Severus also has a fearful personality due to the terrible treatment he received from his father and the marauders. He trusts no one and has no friends.
