Shino Matsueda (Subaru Kimura) publicly stated that his work that won the Naokawa Prize - Spring and Ultramarine - was plagiarized, and the editorial department of Ruishinsha suddenly fell into chaos.Katayama Meiqing (Yuai Shinkawa) hurried to Shino's house, but he was nowhere to be seen.

Meiqing returned to the company, and when she was about to confess that she actually knew about the plagiarism, she was stopped by the editor-in-chief Umemoto Takuma (Masanobu Sakata): “You don’t know anything, you are a victim of betrayal, right?”

Shinobi stood in front of his hometown. Fifteen years ago, despite the opposition of his father Fujio (Minagawa Sarutoki), he insisted on leaving home to pursue his dream of becoming a novelist.

“I'm back.”“Um.” Feeling his father's kindness in deliberately avoiding mentioning the plagiarism incident, Shannan recalled the time during the summer of his first grade in junior high school when his father taught him somersaults.At this moment, Fujio suddenly collapsed...!?“《Spring and Ultramarine》the real author” also takes action...!?
