This was a type of drama where you had to just accept it for what it was and play along with it. It was super cheesy which added to the charm. Hong Xiao Dong's character was WILD and in a normal drama, I wouldn't have liked him, but in this drama, his one-liners were really funny and dorky and I couldn't stop laughing. It was honestly the perfect cure to a stressful week of work - it was something light and silly to watch. After saying that, I gave this drama a 3/5 simply because even though the plot was actually really interesting), the execution was so random. It just didn't flow. I was super invested in the first 18 episodes because the plot was Hong Xiao Dong and Zhang Xian Ting kicking some ass. Even though they are from two different worlds, they somehow always seem to get into trouble together and helping out the two brother guards. The first half episodes were them bickering but learning how to work together and figure out why all of a sudden, when these two guards came into their time that Hong Xiao Dong now has this weird superpower to read other people's minds and turns into a different person when triggered by a sound who is a master of martial arts. These two end up falling for one another, but won't tell the other until the all to classic "someone gets really hurt" scene and that's when they feel is the appropriate time to confess their feelings. It was really cheesy...and terrible, but I was invested. Then out of nowhere, after we get some kind of hope that they will be together, the next 5-7 episodes they aren't even in!! It turns into this completely different drama where all the minor characters become mains. I did like in the first 18 ep that it was about the blossoming romance between our two mains as well as the two brothers learning more about themselves as individuals and not just their emperor's mindless guards. I would say these two pairs got equal screentime. I got invested in their characters and knew that they would kickass and save the world at the end of this drama. Nope. Instead, after this huge event which lands one of the mains in the hospital, the drama shifts, and Mo Han ends of being the main character alongside a completely new character, professor Sun Yan Jun (a childhood friend and historian) who gets introduced randomly around ep 18 and we are expected to be completely invested in his character. Ke Shang comes back and helps Sun try to figure out who the Black Suit boss is and how they are connected to the Ming Dynasty after finding out the drug that the boss uses to control the back suited bodyguards is the same that was given to brother Tian in his time. Mo Han becomes the main character and her story is just her being heartbroken after seeing Hong Xiao Dong and Ting together all the time. While Sun and Ke Shang work together on figuring out the bad guy, they are fighting against each other for Mo Han's heart while trying to comfort her. I honestly didn't like any of the side characters, except for Ke Shang simply because Professor Sun was sus and Ke Shang (was homeboy Peter) was this simple cop who was in love with a down to earth girl. The ending threw me off too. I wanted the two mains to come back and kick some ass, but instead, only Ting came back while Hong Xiao Dong was working behind the scenes (and we never saw him) we assume, kicking ass? Don't get me wrong, Ting had some awesome one-liners, but both she and Dong Xiao Dong started off this drama being badasses - Ting this reporter that would sacrifice her life to know the truth, and Dong Xiao Dong, just being a badass solving crime and defending his woman. After they disappeared, they came back and Ting never went back to her job which was supposed to be her passion in life and Dong Xiao Dong never had a cool fighting scene again!! Like what is the point of having this alter ego who was a martial arts master and never fighting? Even at the final boss battle in ep 28...he was NOWHERE. Yeah, he was given the mission to save the mayor, but no one else could have done that?? He's the main character....why wasn't he at the final battle?? But one of my favorite things about this drama was when Hong Xiao Dong found out how he was connected to his alter ego and how Zhang Xian Ting was connected to it as well, and their love story that technically survived hundreds of years. I think if this was a better drama, they could have done so much more with this romance story, but for what this show was, it was pretty damn cute.
