I am also currently watching. So far it's the best drama of the year. I really like the characters and the bromance. Perfect scenarios, costumes, cinematography, soundtrack. Good action scenes and fights. The best are still the characters and the dynamics between them, especially between Zhou Xu, Wen Xing and Cheng Ling.
To tell you the truth, I'm a little disappointed in this drama. Always the same story: two best friends falling in love with the same girl. Nothing new.
