A Young Man on a White Horse Is Drunk in the Spring Breeze and a Hundred Miles of Rain

(You can just quit the book if it doesn't look good. No one is forcing readers to read it.) This article is about Ye Dingzhi, also known as Ye Yun, who has been engaged to Baili Dongjun's sister Baili Yuhan since childhood, and Ye Yun has liked Baili Yuhan since he was a child. He met Yi Wenjun entirely because she was Baili Yuhan's good friend, so Yi Wenjun met Baili Dongjun and Ye Dingzhi, also known as Ye Yun, and the four of them became good friends after that.
