Wu Yunxi did kill Min Xueya in "Top Floor". Wu Yunxi was drunk and pushed Min Xueya down the stairs so that his daughter could go to Qingya High School. In the first season, when Zhu madly pushed Xueya with his own blood, drunkenness appeared. I saw Zhu trying to push Xueya away. Touching the vase carelessly, Zhu was afraid to leave. Then Xueya wanted to come down and ask, Aunt, are you here to save me? Wu Yunxi was paralyzed by alcohol, thinking that Xueya was dead, her daughter could enter elegant art, and Wu Yunxi pushed Xueya down.

In the play, Wu Yunxi is Luna's mother and an unqualified real estate consultant. As a student, she used to be a very powerful soprano, but she gave up vocal music because of the fatal injury to her vocal cords. After that, the husband fell off the railing and died because of drunkenness, and his money was squandered. After her daughter luna was born, she has been stubbornly living, aiming at the nouveau riche, seeking a secret apartment for them to earn living expenses, and then relying on the information of the murderer to get rich overnight.

Wu Yunxi, all the children of the chaebol living in Hera Palace bullied Xueya, and Xueya got the evidence. They were afraid, and then Qianshi imprisoned Xueya, because Xueya photographed the evidence that Qianshi was unfaithful to President Zhu, so Qianshi imprisoned Xueya, and then Xueya escaped at the party and was pushed down on the top floor by Wu Yunxi, because her daughter luna was one short of elegance, Xueya first and Xueya first.

So after getting drunk, Xueya retired from the top floor, which was also the hand ratio of President Zhu. Then President Zhu encouraged other chaebols to dump Xueya's body and clean up the scene. Other chaebols dumped Xueya's body for the sake of her children, because Xueya had evidence. They actually participated in Xueya's death, but Wu Yunxi personally told Xueya to push it down, so Wu Yunxi was the direct murderer.
