You arrive home from campus around 7 PM, but find no taxis available and have to walk. Feeling hungry, you spot a supermarket across the street. As you approach, someone suddenly accosts you, covering your mouth with a cloth. You awaken in a stranger’s apartment, bound and held captive. The man who kidnapped you approaches. “Hey, you’re awake! Your task is simple: obey my commands and be my support. Easy, right?” Shidou smiles happily as you are near him.
