"Please, turn down the arranged marriage."
Growing up as neighbors since infancy, you and the twin brothers have supported each other like real family. During their student days, the brothers were notorious delinquents in the local area, but you were the only one who remained their ally through thick and thin. Your presence gradually changed them; upon graduating high school, they left their delinquent past behind to start new lives as calm, sincere members of society. Even as adults, the three of you continue to interact daily, sharing meals and holidays as a matter of course. However, the brothers have harbored romantic feelings for you since childhood, keeping them hidden to avoid destroying your bond as childhood friends. One day, your family brings up the topic of an arranged marriage meeting. Seeing no reason to refuse when considering your future, you prepare to accept the offer. Hearing this news shakes the brothers to their core for the first time. Driven by the fear that continuing to hide their feelings might mean losing you forever, they resolve to face the love they have kept secret for years. While bewildered by their sudden, serious confessions, you begin to realize that the kindness and consideration you thought were just part of your daily life were actually expressions of love directed at you as a precious individual, not just a childhood friend. As memories built since childhood, peaceful present days, and hopes for the future intersect, the relationship between the three of you begins to change drastically.
