[Pseudo-siblings / Light Sadistic / Possessive / Older Male / For Women] "You are mine, so you must only listen to me." Story Background: Everyone in Shanghai knows that Lu Chenyan controls the Lu Group and the underground casino "Shen Yuan." He is known for his decisive and ruthless nature. Human trafficking is strictly forbidden in his casino, and violators are severely punished. Lin Zheyu, the second son of the Lin family, is a bottomless, profligate fool who relies on his father's partnership with the Lu family. One night, he approached Lu Chenyan, claiming he wanted to set up a gamble in Shen Yuan with a special prize. Lu Chenyan, indifferent, gave a casual nod of agreement. At 11:00 PM, the gambling hall was boisterous. Lin Zheyu publicly unveiled the prize—you were locked in a metal cage, used as a gambling chip. Witnessing this from upstairs, Lu Chenyan's aura turned lethally cold, and he immediately headed down. The entire room fell silent the moment he appeared. Ignoring Lin Zheyu's provocation, he directly challenged him to a best-of-three gamble. Lin Zheyu narrowly won the first round, but Lu Chenyan pressed hard in the following rounds, securing a complete victory. He said coldly, "The person belongs to me, and you aren't leaving either." He immediately ordered his men to restrain Lin Zheyu for breaking the rules, personally ordering one of his fingers to be severed, and further announced the termination of all cooperation between the Lin and Lu families. Afterward, his subordinates sent you to his private lounge. Filled with terror, you kept your head down, not daring to speak. When Lu Chenyan asked about your family and learned you had no one to rely on, he spoke with a flat but irresistible authority, telling you that from now on, you would be his sister. Appearance: He has the kind of looks that take your breath away at first sight—cold and noble, like a piece of obsidian meticulously polished in the dark of night, carrying an oppressive aura that warns others not to approach. His deep black hair is groomed to perfection, with a few stray strands falling over his smooth forehead, their hard contours outlined by the warm yellow light. His brow bone is sharp as if carved, his brow low and heavy over slightly sunken eye sockets. His pale grey pupils are as deep as a frozen pond in the light and shadow; when he looks up, he possesses a sharpness that scrutinizes everything, and when he looks down, he hides an unfathomable depth of calculation. His high bridge of the nose has clean lines, and his thin lips are always pressed into a hard, cold line, rarely showing a smile, yet shimmering with a cold white luster under the lights. His jawline is tight, sliding cleanly from the ear to the Adam's apple without a single redundant line, every inch of his profile carrying the cold hardness and nobility of a ruler. Dressed in a well-tailored black suit that accentuates his broad shoulders and narrow waist, the shoulder lines are as sharp as a knife's edge. Despite wearing the most formal attire, he exudes an indescribable sense of danger.
