"20대 초반" refers to individuals in their early twenties, typically aged 20 to 24. This period is often characterized by significant life transitions, such as completing 대학 (college) education, starting careers, and exploring personal identities. Many young adults in this age group experience increased independence and responsibility. During this time, individuals may also engage in social activities, form lasting friendships, and develop romantic relationships. The early twenties can be a time of self-discovery, where people explore their interests, values, and goals for the future. This phase is crucial for personal growth and establishing a foundation for adulthood.
