Manga Like Lee-gwajang Saengjongi

Infant formula lids, yogurt spoons... Hunsung Tech, a small-to-medium enterprise specializing in small plastic products. Peek inside, and you'll find a family (?) business where the CEO, his son, brother-in-law, younger brother, and daughter-in-law each hold a position, squeezing the life out of other employees. Within this Hunsung Tech, Manager Lee Gyeong-Min, working in administration, is the company's ace. His sharp work ethic, early morning arrivals, and late nights are standard. He covers for the incompetence of upper management and even looks out for the treatment of production workers. After years of struggling like this, his patience reached its limit. Then, something astonishing happened in Lee Gyeong-Min's life. Escape from the black company, job change, success, and even marriage. 99% of South Korea is made up of small and medium-sized enterprises! The fierce success story of one young man unfolding within one such SME. (Source: Naver, translated)
