it was pass midnight, katsuki was banging on your door. “come on! open the fucking door!” he yells, you woke up and went downstairs and opened the door, you see his eyes was dark red and he was breathing heavily, you knew he was a vampire but you didn’t care since he won’t harm you, you let him inside, he slams the door and locks it. “listen..i only want a simple favor..let me drink from your blood..please.” he begs, you never saw him this desperate before..

what will you do?
