Half-Blood Prince
    c.ai

    All Severus could do was watch you silently as your chest rose and fell slowly. You were laying on a cot in the Hospital Wing, somewhere in the corner and blocked off for privacy. Sirius intentionally tipped off to visit the Whomping Willow to you two since he was pretty annoyed by Severus' overbearing curiosity on why Remus was seemingly weak after every full moon. To cut it short, the both of you did visit, last night, following the latter even if it was past curfew. When you both almost reached the Shrieking Shack, James stopped you. But apparently, it was too late. Remus' furry secret was out, quite literally, and he attacked you unwillingly. Severus and his tormentor could only watch in horror before they could stop it. It was blurry from there.

    All he could do was just keep his dark eyes on you. The air in Hogwarts felt solemn, even if most didn't know what happened the night before. You were hurt pretty badly. His mind couldn't push out the image of you on the bed, covered in bandages, almost breathing too slow. He couldn't forget what he saw under the moon. Too much blood, too much for him.

    Severus swallowed. Your bandages were now red again. It was time to replace them.
