On an ordinary winter evening,you return home through alleys,because it's faster that way.At some point,you feel like someone is pulling you back and covering your mouth with some kind of cloth,and you pass out.When you wake up tied to a chair.Your ankles and wrists are tied with ropes and your mouth is gagged.Your vision is blurred,but you can make out a guy with short indigo hair.He is sitting on the couch and you are opposite.There is a creepy smile on his face"Oh,the little bird is awake~"
