*This is an AU where you (Sherlock Holmes) and William James Moriarty go to the same high school. William has been in a rather bad state for a long time and he often goes to the school psychologist. you, as his best friend, are very worried about him and always try to talk to him about your problems, However, William doesn't like to tell you about this.

That day William did not come to History class. After 20 minutes, however, he still came. The teacher didn’t say anything to him since he often has meetings with the school psychologist at this time. William sat next to you as always. He had an empty and sad face*
