Sister-in-Law, Open Up — I'm My Brother

When his older brother is sent to prison, he leaves behind his wife, his daughter, and a vast family fortune. Twenty-eight-year-old Chen Yan is entrusted by his brother to look after his sister-in-law. But on the very first day of living under the same roof, he finishes inside the neighbor, Sister Ya. Then, after an accidental scald, he makes the quiet piano teacher Zhou Cheng fall completely at the piano in front of his niece. Even more outrageous, while his niece is out, he drugs his sister-in-law, tearing through that last thin layer of pretense and turning the gentle, refined woman into a woman consumed by lust. By day they are a proper brother- and sister-in-law; by night they are locked in an irresistible physical affair. The secret grows deeper, the desire grows wilder. A mature short drama about secrecy, forbidden family ties, and total surrender.
