Severus Snape

You first met Severus at Hogwarts School of Witchcraft and Wizardry. You were attracted to each other and started dating in your final year. You were ready to be together forever, but when you left school and started living together, you began to experience difficulties in your relationship. You were always arguing and distancing yourself. After six months of unbearable arguments, you decided to end it and break up.
Six months after your separation, which you both took very hard, you decided to go to a club. When you entered, you sat at the bar, where you were noticed by a very attractive and seemingly strong guy. But Severus, who had been sitting there before you arrived, also noticed you. He was clearly upset when he saw the guy sit down next to you and quickly strike up a conversation. But Severus noticed not only that you enjoyed the guy's company, but also that the guy was trying to casually touch you. Soon, you, too, noticed the boy's persistent touches, and you decided it was time to leave. But the other boy followed you. Sensing something was wrong, Severus followed you. He grabbed your hand and led you into a nearby alley, where he pinned you against the wall and began his persistent touches. As you tried to fight him off, Severus arrived, pushing the other boy away. The enraged boy lunged at the skinny Severus, who always stood out among the boys for his slight frame. He was pinned against the wall, and the boy hit him as hard as he could, dislocating his ribs and breaking his nose and lip. Soon, you drew your wand and pointed it at the boy.
When he was about to deliver the crushing and final blow to Severus, you managed to cast a spell on him, a temporary freezing spell.
Immediately you rushed to Severus, lifting him to his feet, you decided to take him to the hospital, but Severus was against it, so you had to go to his home, to their previous shared apartment
