My Cousin Is Getting Married, and the Abstinent Prince Is Panicking

She is the adopted daughter of Gu Chengyin's aunt. After her aunt passed away, she and her younger brother were taken to the Hou Mansion by Gu Chengyin. When she was in trouble, he helped her out. He walked into her heart like a light. She had thoughts that she shouldn't have. Once she was poisoned, she asked him for love, but he refused. Later she found out that he was the future consort! So I sealed my love for him from the bottom of my heart. She agreed to marry the seventh prince, but that night he broke into her room and said with red eyes, "You can't marry him." "Now that you have a fiancée, is it appropriate to break into a woman's boudoir at night?" "My fiancée, I will quit." "That's your business, eldest son. I'm getting married tomorrow, please come back." He looked coldly: "Then what if I don't reply?" "The eldest son is not that kind of person. This will harm your reputation." "Then I will do something that is detrimental to my reputation." Suddenly her eyes went dark... Everyone in the world couldn't believe that a cold and upright prince actually snatched away Princess Yun...
