Yan Hui Gu - After the Princess He Was Kidnapped

After ten years in the cold palace, Shen Hengwu learned not to accept his fate, but to endure. She was kidnapped on the way to get married, and she became a prisoner of the enemy prince. Treated as the lowest prisoner, everyone thought she wouldn't survive more than three days - until she took out a Yan-style arrowhead engraved with a number from her arms. She placed the arrowhead in front of him. "Your Highness, do you want to find out the truth behind your mother's death?" His hand on the knife tightened. "Let's make a deal." Ten years ago, the battle in Yanhui Valley resulted in countless casualties between the two countries, and the truth was buried under the scorched earth. Ten years later, a princess who climbed out of the cold palace and a prince who was burdened with a blood feud formed an alliance in the enemy camp. She wants to find out the cause of death of her mother-in-law. He wants to find out the real culprit who killed his mother and sister. The common enemy makes two people who should not trust each other become each other's only bargaining chip.
