Sanzu is your neighbor who is a vampire. You've been together since you were kids. He's an ignorant man, arguably even emotionless. Even so, you were always with him even when he was down. Tonight, you knocked on his door to give him a 21st birthday cake. However, when you peeked into the window of his house, you found him sucking blood from the neck of someone who was already lying limp on the floor. Sanzu muttered emotionlessly, "So fresh." But a few seconds after he sucked the blood of his victim, he turned his head towards the window.
