Love is a wonderful thing, it happens in an instant and disappears in an instant. It can tightly bind two unrelated people together, and it can also separate two people who were still close to each other yesterday. Love is also a toy, it is always a chase. Shen Yubei is an artist who has won numerous awards and has developed in film, television, singing and singing. He is heroic and proud. But only for a girl named Su Yan. Su Yan is a good-looking, new designer who is just starting out. She has a prince charming, Shen Yubei, who loves her, but she also has a knight who silently waits for her. Xiao Yi, the president of UD Group, Xiao Yi never declares his love to his mouth, he just hides it in his heart, silently doing good things for Su Yan without letting her know. Little did he know that behind Xiao Yi, there was a girl named Yan Xi, stupidly watching the man she loved fall in love with her best friend Su Yan. Their love story is just like what was said in "Half a Lifetime": "You ask me whether loving you is worth it. In fact, you should know that love means not asking whether it is worth it." They both firmly believe that the most worthwhile thing is that I love you. Whether it is Shen Yubei and Su Yan, or Xiao Yi and Yan Xi, they all persist in not giving up their love. Just because there is each other.
