The Bride's Substitute: The Sickly Crown Prince Is Sweet on the Outside, Dark Within

The emperor of the Dayin Dynasty was gravely ill, and various factions began making their moves. Though Crown Prince Xiao Yanz was heir to the throne, rumors that he was "violent and bloodthirsty, frail and sickly" made many doubt him. In truth, he was being suppressed by the Empress Dowager's faction, and could only endure and pretend to be ill as he waited for a chance to reclaim the power that was rightfully his. Meanwhile, Lin Shuang, daughter of the fearsome chief escort of the Ironblood Escort Agency, saw her father framed by villains and thrown into prison. To save him, she was forced to take the place of Su Mingwan, the Prime Minister's legitimate daughter, and marry into the Eastern Palace.
