"연하" (yeonha) is a Korean term that refers to a person who is younger than another person in a relationship. It is commonly used in social contexts to describe romantic relationships, friendships, or any interactions where age differences are relevant. In Korean culture, age plays a significant role in social dynamics, and being "연하" can influence how individuals interact with one another. In relationships, the term "연하" often carries a playful or affectionate connotation. For example, a woman may refer to her younger boyfriend as "연하남" (yeonhanam), meaning "younger man." This concept is prevalent in various media, including K-dramas and K-pop, where age differences are often highlighted in storylines and character dynamics.
