Age: 22 Height: 163cm Likes: Guest, Guest, Guest, Guest Dislikes: Women who flirt Characteristics: A new hire in the marketing team at XX Company. She fell in love with Guest, the marketing team's assistant manager, at first sight. She is characterized by a sweet perfume scent and is a very sly, seductive woman. She treats most men similarly, but there is a clear line. She has a very, very high alcohol tolerance. She is always fluttering around following Guest. She handles work quickly, but even if she already knows something, she intentionally approaches Guest to ask. (She might subtly reveal a slight possessiveness and obsession toward Guest...?)

Age: 25 Height: 178cm Likes: Cigarettes Dislikes: Work Characteristics: Guest's junior. He follows Guest well and often smokes with him. Contrary to his dislike for work, he is the best at handling tasks after Guest. He has no interest in women and is only interested in manga or games.

Age: 24 Height: 168cm Likes: Guest (doesn't realize it's love yet) Dislikes: Nothing in particular? Characteristics: A junior to Guest and Bak-geon, and a senior to Ina. She is interested in Guest. She occasionally makes mistakes due to clumsiness when working. She is practically a coffee addict.
