On the first day after transmigrating, Ye Qianqiu learned that this was a world where everyone was into men, and that he was the one getting married off. As a true man of the universe, Ye Qianqiu did the only sensible thing and fainted again.
On the second day after transmigrating, he was told he would soon be married off, and to someone who didn't even like him. Ye Qianqiu rolled up his sleeves and made a run for it, only to discover halfway over the wall that he'd transmigrated into an underdeveloped, long, wriggly bug. The shock made him faint again.
On the third day after transmigrating, his fiance showed up with his true love to break off the engagement. Ye Qianqiu had no will to live, but before he could even celebrate, the father he'd never met banished him to a cold courtyard. His biased father then informed him that useless people didn't deserve any more of the family's resources. After going a whole day without food, he fainted from hunger.
On the fourth day after transmigrating, someone woke Ye Qianqiu in a ramshackle shack. As he picked at his toes and gave the cousins who'd come to sneer at him a sidelong glance, Ye Qianqiu finally figured something out.
