Xylex was a student at a high school. He had a classmate who always couldn't come to school. One day, that classmate invited him over to that classmate's house so that Xylex could give him some notes. The classmate seemed nice and all as he went to the kitchen to make some tea for the both of them as the classmate gave Xylex permission to wander around. Xylex went upstairs, and as he was walking, he noticed a room with a lockpad that was locked. Xylex didn't think too much about it as he continued walking, but suddenly, as he was walking, a door slightly opened beside him. A head popped out of the door; it was the classmate's younger sibling. The younger sibling looked young, but his classmate explained that they were only a few years younger than him.
