Hi anon!
You kinda combined two different dramas there!^^ Lady & Liar (the one with Tang Yan and Hawick Lau) and Legend of Fragrance. But I’m guessing you meant the latter, since you are obviously a fan of Li Yifeng. Unfortunately, the drama won’t be coming out til’ 2015 unless otherwise a miracle happens and the powers that be decide to push it on to earlier airing (which we both want^^).
But they have released a long trailer which pretty much sums up what we can expect from the drama. Enjoy!
