Seo Eun-Yu, the youngest employee in her second year at Baekmoon Group, belongs to the TF team led by Baek Ki-Jo, the grandson of the founder Baek Ki-Cheol. Known as a talented person who studied abroad, Eun-Yu's true identity is a spy under the order of Choi Seolhwa, Ki-Jo's new mother and political enemy! However, Eun-yu, who fell in love with Ki-Jo the moment they met, is flustered when he unexpectedly confessed his feelings. "Just for one month." "Not as a boss but as a man, date me." Unable to refuse Ki-Jo's offer, Eun-Yu begins a tightrope walk between Seolhwa, who is watching her every action and Ki-Jo, who is boldly approaching her.
