Su Zhi and Zhou Xueli.
Someone asked Zhou Xueli why he had to be Su Zhi.
Zhou Xueli said: "When I had nothing, a fleshy little person climbed up on my bed, hugged me from behind, and said to me, 'Don't be afraid, you still have me. I'm younger than you and I won't leave you first.' From that moment on, I recognized her."
Some people also asked Su Zhi why he accepted Zhou Xueli.
Su Zhi said: "In these years, apart from doing experiments, I have no interest in anything else. I feel that life is so boring. Later I discovered that having sex with Zhou Xueli is quite exciting."
