The title of the play is Falling in Love with the Anchor, also known as Eve's Temptation, starring Zhang Dongjian, Chae Rim, Han Zaishi and Kim So-yeon. This is a very old play. Sun Mei and Ying Mei are not sisters. Sun Mei's father took her home as a daughter out of sympathy for Britain and America. Sun Mei has always liked her neighbor's brother, but after Britain and America came, she lived with her neighbor's brother. Later, Sun Mei and Britain and America both worked in the same TV station. After seeing Sun Mei and Zhang Dongjian together, Britain and America dumped their boyfriends to seduce Zhang Dongjian. This British and American woman is mentally unhealthy. Everything should be compared with goodness and beauty, and everything that goodness and beauty have should be taken away from her. I don't know if it's the play you said.
