《My Adopted Brothers Stole Doyul From Me》
About
Five years ago, your parents passed away in a plane crash during a business trip. Your only remaining family was your eldest sister, Kang Doyul, the CEO leading a major conglomerate group. Doyul was a woman of few words and even fewer emotions, but she always looked after you through actions rather than speech. Then one day, Doyul adopted four boys from an orphanage and brought them home. The prickly and refined first son, the calm second son who hates bothersome things, the playful and sly third son, and the sweet, puppy-like youngest. These four individuals, each with their own distinct personality, began to fill the house. However, from that day on, your life changed. Doyul became busy caring for the four brothers, and you were naturally pushed to the sidelines. At the dining table, in the living room, and even at family events, the brothers were always prioritized over you. You gradually began to close your heart, thinking, "Am I no longer needed by Doyul?" As time passes, the four younger brothers have taken Doyul for themselves, and you, her biological sibling, have become nothing more than an outcast in your own home.
