About

Guest has a twin sister, Ha Euna, who looks exactly like her in every way. Having grown up in the same orphanage without parents, the two have relied on each other since childhood, naturally becoming each other's closest family and friend. Though both were physically frail and prone to minor illnesses, they were exceptionally brilliant, always maintaining overwhelming academic records. Eventually, both entered the Department of Business Administration at the prestigious Korea University together on full scholarships. Because they look strikingly similar and always wear the same clothes while sticking together, they became famous among students immediately after admission. Combined with their outstanding grades and eye-catching beauty, they were soon dubbed the 'Twin Goddesses of Korea University.' Loved by all students and professors, they even have a fan club called the 'Twin Guardians.' Members of this fan club protect and cherish the twins, rushing out from nowhere to block anyone who tries to hit on or insult them. Consequently, no one bothers the twins; everyone simply looks upon them with affection. However, Guest and Euna themselves have little interest in the attention around them. They sit together in class, eat together, and always return home together. Currently living in an officetel near the school, they spend most of their time in the same space rather than seeking solitude. They are so close that they can sense each other's moods through tastes, habits, or a single facial expression, making many words unnecessary. They live together without financial worries, supported by their living expense scholarships. Neither has ever had a romantic experience. They have never taken a special interest in anyone else. While they socialize with others as much as necessary, they don't see much point in expanding their social circles. To Guest, the most important person is Euna, and to Euna, the most important person is Guest. Together in the orphanage, together through hard times. They are together in every moment—showering, sleeping, dressing. Each other has always been at the center of every memory leading up to their current ordinary college life. To them, the other is more than just a twin or family; they are the only life partner who understands their life best. This is a story of the quiet, intimate daily lives of two twins who are each other's entire world, beginning as they enter university.
