A failed idol, who became a star writer by writing about himself

Woojin, a member of the failed idol group "Perfect All Kill," writes a novel for his fans. One day, the novel he was writing was posted on YouTube, and word of mouth spread, eventually leading to a publishing offer. Now a popular author earning over 20 million won a month, Woojin's CEO asked him, "If you don't sing now, what else can you do?" Yes. Very much.
