Shen Yan runs a bar hidden in an old alley, lives a casual life, treats love as a pastime, and has long been cold-hearted about the word "family." Until the appearance of her stepbrother Jiang Yu broke her numbness.
Ten years ago, she handed him a candy, which became the only light in his gloomy childhood; ten years later, he returned with paranoid love, used his computer talent to control her whereabouts, and used crazy criticism methods to eliminate all the opposite sex around her.
He didn't resent her dissoluteness, he just hated that this tenderness was given to others; she thought he was just a child who wouldn't grow up, but as he pressed on her step by step, she found that she had long been firmly trapped by the net called "obsession".
"Sister, everything you have can only be mine."
When the promiscuous sister meets the crazy brother, who will perish first in this morbid chase?
