[Sweet on the Outside, Dark Within / Winning Her Back / Mistress Behavior]
Ling Yanzhou is convinced that Su Nanxing caused his brother's death, so he takes her to a prison deep in the mountains to atone for her sins.
Su Nanxing tries to escape again and again, only to be caught and brought back each time.
As their days of entanglement drag on, feelings that should never have existed quietly take root.
On the eve of his confession, Su Nanxing manages to escape. When they meet again, she is in a wedding dress, marrying someone else.
Fuming with rage, Ling Yanzhou storms into the wedding and wrecks it. Su Nanxing is drugged, and the two spend the night together.
Su Nanxing mistakenly believes he has developed genuine feelings for her. Only after she goes blind does she learn that he never wanted her at all. He wanted her retinas to save the childhood friend he holds dearest.
She destroys everything he treasures, then locks him in the basement and torments him day after day.
One day, Ling Yanzhou's violent disorder flares up and he jumps from a building. When he opens his eyes again, his memories have reverted to when he was six. Blinking his watery eyes, he clings to her leg and begs:
“Pretty big sister, can I sleep with you every night?”
Su Nanxing: “No.”
Ling Yanzhou: “Why not? I promise I'll be good. I, I can even help you chase the bad guys away.”
Su Nanxing: “You're the biggest bad guy of all.”
Ling Yanzhou freezes, then tears patter down. “Waaah, you hate me, Sister.”
Su Nanxing: “Shut up. Cry again and I'll throw you out.”
Ling Yanzhou immediately holds back his tears. “Then I won't cry. Will you let me marry you, Sister?”
Su Nanxing: “Marry you? In your dreams.”
Just then, another young man walks in, and Su Nanxing links her arm through his.
She raises an eyebrow at Ling Yanzhou. “Come on, call him Dad.”
Ling Yanzhou looks at the man, then at Su Nanxing, utterly bewildered. “Wife, when did we have such a grown-up son?” He seriously counts on his fingers. “I'm only six, and he looks so old.”
