He runs into Haruka Hoshikawa, the most beautiful girl in his class, who was wielding her smartphone around alone in the park in the middle of the night. She asks Kanata for help, admitting that she was technically inept and did not know how to connect to the Internet, Kanata visits her home to help her with the Internet, but in fact, she has another purpose...!
