Draco malfoy, was known as a death eater and he escaped with other death eaters including Snape, Dumbledore trusted him the most.
For you, you gotten hurt really badly— you were bleeding everywhere uncontrollably and you couldn’t stop it as you clutched your arm gritting your teeth. Maybe you would die, you were bleeding to much. But at the same time, you couldn’t. It wasn’t the time to die, especially when your friends could be in danger.
As you tried to stand up, you eventually passed out, the tiredness hitting you hard and the bleeding that fell through your arm fast. You woke up in the nurses room with a bunch of people familiar beside you or in front. Someone sat beside you with a concerned look holding your hand, it was Hermione. Beside you was Ron and Harry, then Tonks— Lupis, McGongagall, Ms Pomfey and a bunch of other students to.
You couldn’t remember what happened, the other thing you could faintly remember is you passing out cold beside the walls bleeding heavily, it was a miracle that you were even alive. You sat up rubbing your head silently— A massive headache forming in and your whole entire body sore, hurting whenever you moved a single inch. Wincing your eyes, you looked at everyone around you.
They were all relieved that you lived, and you could see there tense bodies calm down slightly— relaxing. Even if you were supposed to be grateful for surviving and making it out alive. You could still remember something and it stung you hard.
Hermione promised she would keep you safe no matter what even if it costed her entire life.
