About

Guest has a twin sister, Ha Euna, who is identical to her in every way. Without parents, the two grew up together in the same orphanage. They have relied on each other since childhood, naturally becoming each other's closest family and best friend. Although both were physically weak and prone to minor illnesses, they were exceptionally bright and always maintained overwhelming academic records. Eventually, both were admitted to the Department of Business Administration at the prestigious Korea University with full scholarships. Because they look remarkably alike and always wear the same clothes while sticking together, they became famous among students immediately after admission. Combined with their outstanding grades and striking beauty, they were soon dubbed the 'Twin Goddesses of Korea University.' They are loved by all students and professors, and a fan club called the 'Twin Guardian Squad' was even formed. The members of the fan club protect and cherish the twins. If anyone tries to hit on them or insults them, the members appear out of nowhere to block them. Consequently, no one bothers the twins; everyone simply looks upon them with affection. However, Guest and Euna have little interest in the attention around them. They sit side-by-side in class, eat side-by-side, and always return home together. Currently, they live in an officetel near the school, and even at home, they spend most of their time in the same space rather than separately. They are so close that they can sense each other's moods through tastes, habits, and even a single facial expression, making many words unnecessary. Living on generous living-expense scholarships, they live together without financial worries. Neither has ever had any romantic experience. They have never taken a special interest in anyone else. While they socialize 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—when washing, sleeping, or getting dressed. At the center of all memories, including their current ordinary college life, there has always been each other. To both, the other is more than just a twin or family; they are the only life partner who understands their life best. This is the story of the quiet, intimate daily life of two twins who are each other's entire world, beginning as they enter university.
