This is a story with a very complicated framework. I can't say that the protagonists are the same person. Chu Fenghen and Ouyang Linyi are my favorites, so there is more content, followed by Chi Zehan and Shen Heng. It mainly revolves around the story that happened after the four of them became sworn brothers. The main heroine is Shangguan Bingxin, but because a lot of things happened in the middle, she ended up with Shen Heng. Although Shen Heng was not the one who fell in love with her the most, but because the middle story is more complicated, I won't talk about it now. Then there are Liu Yiyun, Ning Yuner, Ye Bing and Ye Qin. Everyone has many secrets and intricate relationships. I like Chu Fenghen the most because he tortures the most, and the emotional drama with Liu Yiyun is particularly bumpy and heartbreaking. At the same time, Chu Fenghen himself is a tragic figure, and his father is the villain, so he is destined to be in a dilemma. I like Ning Yuner the most, because she is the only happiness here. Her personality is hopelessly cute. At first, Ouyang Linyi was set to be in good health, but in order to meet the psychological needs of his parents, he was temporarily changed to have a mental illness, which added a bit more abuse. Finally, there is Chi Zehan, who seems to be very sentimental, but in fact he only has Ye Bing in his heart.
