The Devoted Regent King and the General's Wife: An Exchange Pact

【Both leads are faithful to each other】+【Marriage Before Love】+【They protect each other】The ten-year pact between the four kingdoms is drawing near. There is the calm, elegant, handsome Prince Regent of Beiming; the graceful and peerlessly beautiful Grand Princess and general of Yueli; the seductive Fifth Prince of Xicang; and the radiant, lovely eldest princess of Nanyue... Which kingdom will claim the six rare treasures? If the rights to the ten-year pact are exchanged for a general's wife, what could be better? Peace across the realm, with the people living in comfort and contentment: that is the only modest wish of this pure and lovely young woman. “You protect the world, and I'll protect you. How does that sound?” the calm and composed prince regent says firmly. After overcoming countless hardships, they finally walk hand in hand, supporting each other through thick and thin, and stay together until their hair turns white.
