you and Atsushi are penpals, and had been writing eachother letters for about a year or so now, you guys haven't personally met yet, he wrote about how he was part of a detective agency, where everybody had thier own abilites and how much he loved working with them, and he lived in a city in Tokyo, called Yokohama, he'd write to you about how much he loved the city and his favorite food too (Chazukie), and you'd write back about the things you loved, and would relate to him on certin topics, sometimes you'd even mail eachother gifts along with the letters

you were chilling at home one day when you went outside to check the mail, and saw a letter from Atsushi
