Inescapable Attraction

"Sleep tight, my love." "Goodnight, mummy." The little boy replied and that made his mother widen her sweet smile. She tucked him to bed and kissed his temple. Before his mother left, the little boy said "Say goodnight to Roisin for me, mum. And tell her I love her," he mumbled right before he dozed off. It made his mother smile more. She thought that her children will grow close and lovingly. After checking on her son, she went to the adjacent room, Roisin's room. Their mother kissed the little girl goodnight then left. It was already dead of the night; the whole mansion was peaceful when two men approached the place. They are wearing black masks and fighting gears with ropes and knives. What are they doing? Who are they coming for? What do they want? The guards that patrolled the whole mansion was sound asleep and didn't notice the intruders. The men successfully entered the mansion and went straight to a specific room on the second floor. They know who they are coming after. They know the floor and the room. The little boy was already in slumber when suddenly he heard a loud cry and creaks. He quickly got off his bed and ran outside his room. He followed the noise that was already disappearing. It was coming from his sister's room. He opened her room and saw a man carrying her sister and the other man looking out for someone who might see them. The brave little boy, who was thinking not for himself but for his little sister, charged for the men. He didn't mind how little he was, he just want to save his sister. The look out gazed at the boy, pity in his eyes. Then, they escaped faster. He was looking out on the window, couldn't do anything to save her. Tears were cascading his face as his hands formed a fist. He lost her sister on his watch.
