Everyone will have the experience of falling in love at first sight more or less in their youth. The heroine of the story fell in love with the male protagonist Wang Yang at first sight at her best friend's wedding. He came back from Japan to attend her sister's wedding. The two people seemed to be two parallel lines that should not have intersected. Perhaps they met by fate and were destined to meet. A heart-warming story happened in Japan, about Aurora, about Doraemon and Nobita, and about youth. There is no empathy in the world, but as long as we put our minds to it, we are all looking for ourselves.
