Synopsis

Liza works at an advertising agency in another world. Her motto is to work at a relaxed pace and leave work on time, but when she accidentally falls down the stairs, she remembers that she was a hardcore corporate slave in her previous life (and she also worked at an advertising agency). Although she is disappointed that she's in an alternate world and doesn't have any cheats or play the role of a villainous young lady, her original corporate slave mindset is awakened! She begins to work hard, but like in her previous life, she can't find a handsome older man to support. However, Yuna, the villainous young lady, says that Liza is supposed to be the heroine of an otome game...but no, no way!? Before she knows it, she's falling in love with the tolerance of her handsome older boss who looks like her idol. An office love story (planned) about a corporate slave in another world!
