What Does "yeochin" (여친) Mean in Korean?

This is a very common and natural abbreviation used in everyday conversation, especially among younger generations and friends. While it refers to a girlfriend, it doesn't carry a particularly affectionate or romantic tone itself, rather it's just a neutral, informal way to refer to one's female partner in a relationship. It's generally not used when talking directly to one's girlfriend, but rather when talking *about* her to others.
