Mercilessly Manga

A brief description of the manhwa Mercilessly:

Do Janggon is a special forces spy used against North Korea who is also a human weapon. He was apprehended and sent to the “Daesan Welfare Center,” which violates human rights and engages in labor exploitation, after both of his arms became wounded. He would need a month to completely recuperate, the doctor said. He must thus wait it out at the welfare center till his arms are fully recovered.
