Fight Lady

힘내라 여대리, Fight Lady, Fight On! Yeo Manager, Fight On! You Are Manager, Himnaela Yeodaeli, Himnaera Yeodaeri, Держись! Ты же менеджер!

A female manager in a company filled with all the yaoi clichés. All her coworkers are men, gay, and very incompetent, most likely because they are more concerned about their "secret" dating. Only her superior that looks like a broom with glasses seems not to be involved with anyone and keeps yelling at her for any little thing.
