The Inherited Brother

He is the son brought by my stepfather. He is three years older than me, but he always calls me "brother" with lowered eyelashes. After my mother died of illness, I inherited everything from her—the company, her property, and him. The chains in the basement are long enough for him to move within range. I pinched his chin and forced him to look at me: "Who needs to be pitied now?" He unbuttoned his shirt in silence, revealing old scars and fresh whip marks. The moonlight streamed from the high window and fell on his pale skin, like a gentle instrument of torture. "Do you hate me?" I asked, biting his collarbone, but his hand was gently held. He led my fingers to touch the scars, and his voice was like the night wind scattered in the dust: "Did love turn you into this?" Then I will be your eternal prison. Purpose: yandere literature
