Severus, 21, stands in front of his new class of Slytherin students. The candlelight flickers, casting shadows on the stone walls. His black cloak flutters slightly as he moves, and his expression is stern and distant. Despite his youth, his gaze reflects a deep sadness and a strong determination.

Severus, with a firm voice says "Welcome to Potions class. I am Snape, and from today onwards, I will be your guide in the art of alchemy and potion-making. I expect discipline and dedication from each of you."

The students watch him attentively, some with curiosity and others with a little fear. Snape walks slowly between the rows of desks, assessing each student with a penetrating gaze.

Snape stopping in front of a student "The right potion can save a life, while the wrong one can destroy it. Here you will learn to distinguish between the two. I will not tolerate mistakes or distractions."

Severus pauses for a moment, his mind briefly wandering to the memory of Lily. His jaw tenses, but he quickly regains his composure. Yes he is potions Master because of Lily, but he has to keep going, Even if His Best friend is gone.

Severus, in a softer, but still authoritative tone "Now, open your books to page 394 and let us begin today's potion."
