It's a psychological manga set in 1970s and follows the story of Kurumizawa Yoshihiko, a once-popular mangaka who hasn't had a single story published in six years, and is struggling to write a story that could resonate with modern readers. One day he meets Hata Kensaku, an illiterate factory worker and aspiring mangaka who's a fan of his work and was directly inspired by him. Reading Hata's manga and realising his talent, Kurumizawa takes advantage of his illiteracy to fool him into being his ghostwriter.
TRIGGER WARNINGS:
Abuse of authority, exploitation, mild discrimination, depiction of obsessive thoughts, mild confinement, child abuse, domestic violence, blackmail, bullying and harassment, mention of suicide, depiction of war crimes (the Nagasaki atomic bombing), mild violence and blood 』
In my opinion it is definitely worth reading, every chapter is filled with suspense and it literally kept me on the edge of my seat through all 28 chapters! The chapters are also relatively short if you're worried about the length.
