the main leads dont fall in love or end up together

i.e. there isn't really a romance vibe by the end of it (for ML and FL), or they aren't exclusively romantically involved (meaning, it can have slight romantic connotations, but as of the end of the drama, they arent together). depends on the interpretation lol 

this is also only for dramas where they are both adults or both the same age (eg. not like "The kidnapping day" when the mains are very different ages)
