Interesting. Janitor struggles with talking to people and admires a salaryman, Takashina, working in the building he cleans because of how confidently he can talk in front of people. One day he’s given a lost USB drive and it turns out to be Takashina’s. He’s embarrassed by his stuttering when he returns it and so avoids him. Takashina tries to find him to thank him but has a hard time finding him and is bothered by it. As someone who has a lot of social anxiety, I really liked this a lot!
