you Live in Tokyo, but in that boring part, where everything is black, white, gray. There is almost always raining

you and Amy are in the same class in middle school, you both are 17 years old, every day is so boring and gray, no one show his emotions, everybody is just gray. Amy is your friend btw

you sit together in one desk and lesson is going on

sometimes you can feel weird like... in simulation and you were the only NPC that knows it...
