Kang Parang, an ordinary 11-year-old boy, accidentally opened his mother's diary when she was a child. The diary recorded in detail information about each mission she performed. Before he could unravel his doubts, a hand reached out from the diary! The next second, Kang Parang traveled back to his mother's girlhood and became an intelligence agent. His partner turned out to be the same age as him, his mother when she was a teenager! An ordinary, gentle mother who knew how to cook and tell bedtime stories turned out to be an ace intelligence agent with a bad temper and an almighty decathlon when she was a girl!
Kang Parang’ mother Violet also had a dream of being a hero. No, she was a superhero. As a girl, she wore a combat uniform, held a pocket watch that could randomly travel through time and space, and carried a bear schoolbag full of secret weapons. She could fight a way out of the cursed zombie group, and her fighting power was overwhelming; she could play the most rock music, and fought against non-mainstream villains, and her impact is full...
Most importantly, she and her son formed the strongest mother-son partnership in the history of intelligence circles!

Code Name S
This time travel fantasy novel is a story about growth, friendship, and love for a family with a child, including elements of thrilling action and imagination.
Gang Parang finds himself bewildered as he suddenly returns to the present day from the past. His mom tells him to live as an ordinary boy, just like she doesn’t know her past with the MSG intelligence information agency. Following his mom’s words, Parang tries to manage his ordinary school life and forget about the past. One day, a transfer student comes to his class. Ji-Hye is the daughter of Code Name I. Code Name I asks Parang to get along with his daughter, thanking Parang for having saved him from Cosmo in the past. One day, Parang and Ji-Hye get kidnapped by Cosmo’s men. Violet, Parang’s mother who was an MGS top agent in the past, goes into action to rescue the two children. Violet runs into danger while fighting her enemies when Code Name R appears and helps her escape danger. Parang becomes ashamed when he recognizes that Code Name R is his biological father. At that moment, Scarlet appears and tells him that he has to go to the future with her and fight against Ego. Parang says good-bye to his parents and enters the gate of time and space, which opens through Jjakkak-Jjakkak.
