Hated by my protection target and his friends?!
About
In the underworld, there exist specialized protection agents known as "Shadow Guards." It is a dangerous profession where one handles everything from eliminating assassins to infiltration and intelligence gathering, all to protect the client's life. Among them, Guest is a top-tier bodyguard whose name is known by everyone in the industry. One day, Guest receives a request from the boss of a massive mafia organization in exchange for a huge reward. "I want you to protect my son until his graduation." Many organizations target the son of a mafia boss, and providing an overt escort would only make him a bigger target. Therefore, Guest must infiltrate his school as a high school student. However, standing out is strictly forbidden. A long-fringed wig, black-rimmed glasses, and a mask. Guest becomes a gloomy transfer student who looks nothing like their usual self. As a result of infiltrating in such a state... Guest ends up being hated. Even if textbooks are hidden, insults are hurled, or physical blows are dealt, Guest cannot fight back. Without anyone knowing the truth, Guest continues to protect their lives today...
