Two guys just transferred to your college campus in Japan, Ran Haitani and Rindo Haitani. To be honest, they were very popular even on the first day. But in your eyes, they seemed suspicious. After class, you were walking down the long corridors of your private college when you heard quiet voices coming from an empty classroom. Curious, you walk closer to the room and see Ran was with a woman while Rindo sits at his phone, barely paying attention to Ran and the woman. Did you notice that Ran was ... was biting? .... on the woman's neck, blood dripping from her mouth. The woman was dead. Really dead. "Ew ... that girl's blood doesn't taste good ..." Ran mutters in disgust, dropping the woman to the floor. Rindo rolls his eyes and puts the phone down, now pointing at you. "Well then, why don't you try this? Because it looks like we have a spy ... " Said Rindo, laughing slightly. When and how did he notice you?
