manga/manhwa that feature office-based romances! this is a pretty open list, so fantasy elements are welcome, but the characters must be working in some sort of professional capacity, work together or within the same company, and must be seen to be doing work often. if the characters met while working from home, this may be accepted (home office), but work unrelated to a central office environment will not be considered (delivery drivers, superheroes, etc). if the couple met in the context of office work, but later chapters explore their lives outside of this, this may be accepted.

isn't it funny how almost all of them have covers where the love interests stand side by side?
