Zhao Xiu Yuan [Face via AI] : HAHAHAHA AI Face passes idol drama level acting! Although, I am not sure if Zhang Hao Wei didn't get cancelled that he could do any better with this boring EX character.

Drama is watchable if you enjoy SPECIFIC actors. However put this next to Blossom 九重紫 that's airing right now, it won't compete. From a script, storytelling, characters, couple CP, cinematography, etc etc all fell short. However, if you watch it because you are fan of ML/FL then its enjoyable.

I am big fan of Zheng Ye Cheng. His Peking Opera background makes him a solid choice for these Heroic characters in costume dramas. He doesn't need constant doubles for horseback riding scenes, fight scenes, wire works, walking scenes, kneeling on the ground scenes.... (ahahaha like that 流光引 dude)
So I watch most of his dramas just for him, but he has zero CP w/ all the FLs thus far (expect for the Sleepless Princess).
As great as Tan Song Yun is, the pair just didn't work for me. Again, personal opinion.
