HP: Medicine Jar and Platinum Dragon

Reading tips: [Introduction may not necessarily match the content] [No cp, mainly family relationship, the text is super slow-paced] [Watch it as a parallel world that does not conform to the original work] [The character is seriously OOC] [If you don't like it, click on the upper right corner to exit] Signus, the natural potion jar, carries more potions than candies. His daily routine: coughing, drinking potions, and dominating the ceiling of Hogwarts' library and Slytherin common room (because of the star projections there). Draco, the textbook platinum peacock, the king of flying lessons and mobile memes. His life creed: first, I am Malfoy; second, my brother is Signus; third, whoever dares to make my brother frown, my wand will make you regret your birth. Their homework: Signus: Use ancient magic texts to deduce the latest stabilizer formula. Draco: Raise the blood pressure of any Gryffindor with his looks and words. Common topic: How to annoy everyone while still getting professors to give them extra points while cursing. When the Defense Against the Dark Arts class turned into a practical drill, Draco fired curses from the front line, and Signus accurately analyzed the opponent's weaknesses from behind and prepared healing potions. Snape's comment: "At least one Malfoy knew that potions were meant for drinking, not for pouring on Potter." New Hogwarts rules: Don't piss off a sick genius and a brother-protecting maniac at the same time. Unless you want to experience the complete package of being ridiculed by a vicious tongue to the point of doubting your life, and then being "cured" by a bottle of weird-tasting potion. Remember, the most perfect Slytherin is always the buy one get one free one.
