Wen Zhiyu, a scientific research worker, discovered that her boyfriend Cen Ye had cheated on her. When he was about to take revenge, he learned that Cen Ye had died unexpectedly. But the dead Cen Ye suddenly returned, and it was actually the alien predator Ryan from the planet M62 who was hosting him. Ryan only inherited 60% of Cen Ye's memory, imitated human love with clumsy cognition, and devoted himself to protecting Wen Zhiyu. After Wen Zhiyu discovered his alien identity, he planned to observe him as a scientific research sample. Subsequently, Fu Yan, a scientific research colleague, discovered Ryan's traces and set up a bureau to arrest him for his scientific research obsession, so as to drive a wedge between the two. After experiencing betrayal, siege, and life-and-death crisis, Lane escaped with the golden cicada's escape plan, and ended the crisis, spending the rest of his life with Wen Zhiyu, who knew all the truth.
