I remember there used to be a TV series, which seemed to say that a person split into two personalities, then fell in love with two people at the same time, and finally cured by surgery.

Doctor too much, played by Eric Suen Yiu Wai Yaoyao and Ren Quan, the heroine is Luo Haiqiong and her father is doctor too much, but she has a dual personality disease since childhood, and her father can't cure it. During the day, it is a plain question, and at night it is a spiritual pivot. Su Wen is gentle, and Ling Shu has personality. Later, Su Wen liked Eric Suen Yiu Wai Yaowei, and Ling Shu liked Ren Quan. Finally, he had to have an operation, but he could only live one. The two men drew lots to decide who would leave. At first, Su Wen quit the lottery industry, but there were problems in the operation. Su Wen died and Lingshu survived. This is what I saw when I was a child. Nice costume.
