Devoting all one's love to a single woman is simple happiness. If you fall in love with two women at the same time, it will be complicated suffering. And if those two women happen to be sisters, it becomes even more entangled and difficult to separate. However, the beautiful answer lies in who stays with the sunshine, who stays with you; then she or he is guarding happiness, guarding love. Artist Ding Yiming and dancer He Li came together due to their shared passion for art, and thus the lovers eventually became lifelong partners. He Li, in pursuit of a higher realm in dance, left behind her husband and three-year-old daughter Ding Xiaohan, traveling alone to England for further studies. Amidst the struggles of a foreign land, He Li gave birth to her daughter He Fei.
