After Tearing up the Agreement, My Brother Stopped Pretending

She called him brother for eighteen years, but at the coming-of-age ceremony, her heart broke for someone else. He tore up the brother-sister adoption agreement and ended the "legal" distance with his own hands. "I'll teach you what love is, Zhiyu. You can only be mine." From the day she broke into his life, the so-called brother and sister were just an excuse for him to monopolize her. Taboo pulling, extreme paranoia, it turns out that behind the protection is a long-planned fall.
