Evil Through and Through

Yang Sen's study was dark, or at least that's what Yang Lina thought the moment she entered the room. She squinted her eyes to adjust to the darkness and then she noticed that Yang Sen was standing in front of an old painting on the wall of his office. The lights were all turned off, with the exception of a small table lamp that was too small to illuminate the whole room.

"Ehem…" She cleared her throat to announce her presence.

"Lina, who is it that you offended this time?" Yang Sen enquired, surprising his sister.  

"I-I'm sorry. I don't seem to understand your question." she said while approaching her brother. However, when she noticed Yang Sen's cold expression she immediately added: "I don't recall doing anything except for protecting our family, so If I accidentally offended someone then it's not my fault. I was just trying to protect our family."
