Nami works at an underwear manufacturer. The company selects employees who win presentations to lead new underwear projects. However, there's a hidden agenda among the executives. Her boyfriend, whom she secretly dates but can't rely on due to his small penis, her female colleague who she thought was an ally but is actually jealous, and her superior who uses promotions as bait while ignoring power harassment and sexual harassment. It's a full-blown black company with no hope, but Nami, driven by ambition, goes to work every day for herself and societal contribution.
