People consumed by obsessions can fall ill or go mad. Zhou Si helps people rid themselves of obsessions. During one assignment, she met Lin Shiyu, who she said was obsessed with something. Zhou Si: "You're not obsessed. You're just lusting after my looks." Lin Shiyu: "That's right. I'm lusting after your looks." And so this foolish young master from a wealthy family chased after her everywhere, or rather, across every time and space. When Zhou Si went to the Republican era to play a ditzy beauty, he transformed into the son of a warlord. When she went to ancient times to be a traveling doctor, he became a crown prince sent into exile. Zhou Si: "How long are you going to keep pestering me?" Lin Shiyu: "Three lifetimes and seven lives."
