He Yixuan thought that no other girl would come into his heart except Ning Yuqing, but a second girl broke into his world. This girl was called Xu Banxia. Xu Banxia and Ning Yuqing were so similar that He Yixuan had to fall in love with her. But in the end, he was wondering whether he loved Xu Banxia or everything similar to Ning Yuqing. In the end, like Ning Yuqing, she left him...
To this day, he still remembers the last words Xu Banxia said to him: "I am Xu Banxia, and I only promise you half a summer."
