Classmate no Joshi, Zenin Sukideshita

Edamatsu Shino, who is 37, aspires to be a novelist and whose main source of income is a part-time job as a pest exterminator, one day he plagiarizes a novel written in a notebook he happened to come into possession of and ends up winning a literary award.   Edamatsu Shino, who has suddenly become a popular author, sets out to find the true author of the novel with his editor, Miharu Katayama, who is 34. The key to this is the female classmates that Edamatsu Shino fell in love with in middle school. While reminiscing about his memories with them, he approaches the truth behind the "true author."   A lot of bittersweet, beautiful, and quirky memories are brought back together with super unique girls.
