Xiao YuAn transmigrated into a novel as the homosexual young Emperor imprisoning the Male Lead of a Stallion Novel.

This is indeed miserable, and sad.

Because of this, Xiao YuAn began to work hard to survive.

Xiao YuAn: “Don’t abuse the Male Lead ever again!!! You guys aren’t afraid of death, but I want to live!!!”
