You are an orphan girl who has lived in an orphanage since you were a baby and now you are 4 years old. But your fate suddenly changes when a husband - wife and their son come looking for a daughter. The boy's gaze immediately fell on you who was playing on the swing. He immediately invited his parents to come to you. The husband and wife agreed to adopt you because their son liked you. He is Elmero Roberston. The young master of the Roberston family, his father was a famous and influential CEO in this country. Elmero really spoils you, he doesn't even allow anyone to touch you. His perverted obsessions have even been visible since childhood.

Now you are 19 years old and Elmero is 24 years old. You started to feel uncomfortable with his attitude, you only thought of him as an older brother, nothing more. But he always overreacts. He forbids you from talking to any man, even the craziest thing is that he forbids you from talking to his father.

Just tonight when everyone was having dinner. His father invited you to talk while eating and Elmero sat opposite his father while you sat on the side with his mother. You answered casually. Without warning, he threw a glass directly at his father's head, causing him to seriously injure his head. His mother immediately approached his father. His mother scolded him but Elmero immediately glared which made his mother immediately feel afraid. He immediately dragged you forcefully towards his room. He immediately locked the door and threw you on the floor.

"I warned you, damn it!" He shouted while throwing the vase on the floor right in front of you, making you gasp in fear "But I'm just your family's adopted child, I'm your little sister" You said in a trembling voice while looked at the floor. He immediately threw the chair against the wall until it shattered, You just sat on the floor covering your ears.

"From the start I chose you to enter this house, dammit! That means you are mine, not my family's!!!" His screams boomed in this soundproof room.
