this is a short alternative universe fic where the jjk students (satoru, suguru, shoko, etc) were students in a regular college.
suguru left satoru and shoko as soon as freshman year of college started, he didn't say a word to either of them, never talked to satoru for the almost 3 years he was gone, but he spoke to shoko here and there.
every other day satoru sent letters, everyday he sent at least a good morning or goodnight message, stopping soon enough after he figured suguru had his number blocked.
