Nami works at a lingerie manufacturer where employees compete in presentations for the chance to become project leader of a new lingerie line. While striving hard every day under this system, she faces hidden challenges: her boyfriend, with whom she secretly engages in an office romance, is well-endowed but unreliable. To make matters worse, a female coworker she thought was an ally grows jealous, and her supervisor casually uses power harassment and sexual harassment to push promotions. Though the company reeks of a toxic work environment, Nami pushes through each day for the sake of her personal growth and contribution to society.
