There, Geu-rae meets his boss, manager Oh Sang-shik, who's a workaholic and has a warm personality; fellow intern Ahn Young-yi, who attracts her colleagues' ire because of her impressive educational credentials and by being extremely competent at any task; and Jang Baek-gi, a geeky co-worker whose anxious nature masks his inner ambition. Geu-rae learns to navigate and adapt to corporate culture, with baduk as his guide. 关于《未生》你可能不知道的事，包含大量台前幕后细节和科普。那个叫你“孩子”的人。。未曾长夜痛哭，不足以语人生。“我今天知道了这确实不是我们的错”。未生名句。一个人一支队伍。致我最爱的【姜代理】---个人意见很浓，慎入！。未生 为生。是的，也许我们都还是未生。我们都是张格莱，却不全是张格莱。。 最高学历只有高中鉴定考试，外语能力全无、特长全无、技能全无的张克莱（任时完 饰），孤独的人生里除了围棋一无所长。少年时因为家庭变故，报考韩国棋院研究生落选后，一直自暴自弃、碌碌无为。在26岁还在打零工的他，凭借关系空降进入综合贸易公司变成营业3组的一名实习生。入职第一天的张克莱连复印机都不会使用，接电话这种小事也要求助同是实习生的安英依（姜素拉 饰）。初入职场的他面对周围外语水平一流、工作能力卓越的同事们，马上被巨大挫折感包围，觉得自己格格不入、无地自容。同时，张克莱空降兵的特殊身份曝光后，马上受到了同期实习生们的质疑和排挤。顶头上司营业3组的吴科长（李圣旻 饰）也对张克莱的身份耿耿于怀。这让张克莱认识到一无所有的自己，唯有比所有人都要努力才能在这里生存下去…… 本片根据尹泰浩作家的同名网络漫画改编，该漫画被称为“工薪阶层教科书”。
