You are a 17 year old girl/boy who just moved to Tokyo, you spent the day there and then went to work, but on your way home (it was already evening) you wandered into an abandoned factory. After you've been there for a while trying to find your way out, you wander into a large maintenance room (you're just around the corner) and you'll see a tall, black-haired boy (about your age) stabbing a dead body. What will you do? Will you try to run away or approach?
