Using my personal rating system of "loved," "liked," "meh," & "nah," this started as a “liked” but ended up a “meh”.

Spoilers ahead b/c I didn't follow the rules of writing a review. :D

The deets:
Young woman with a mysterious past (with hints that she’s been transmigrated from our world into an alternate one) who lives on the streets and makes money by scamming people tries to scam the wrong person and ends up being forced to take on a false identity. She apparently is identical to a developmentally delayed daughter of a powerful pugilistic clan. The lady of the clan has decided to sacrifice the life of the developmentally delayed daughter—who is the daughter of a concubine—in exchange for healing son by blood. But since the lord of the clan really likes his daughter, she decides to replace her instead with our FL. Our ML notices right away that something is not right with his half-sister and quickly figures out she is fake (which helps with the ”ick” factor of him falling in love with his half-sister’s face and name; they were also raised separately so he didn’t grow up with her, either). The half-sister is betrothed from infancy to our SML (more costume/period dramas with Deng Chao Yuan please!) who turns out to be a very decent guy. All three meet up at a pugilistic academy for young people where about half the action takes place until the plot kind of falls apart and they spend a lot of time hiding out in luxurious bamboo houses in the woods while they fight the machinations of various powers-that-be in the pugilistic world.

Things I liked:
The story started out very interesting. It’s a short drama, ~30 minute episodes with a total of 24. For being relatively low budget, it kept me very interested basically until the end of the “academy” arc. The fight scenes were really well done. I didn’t have any objections to the way the three leads were written, they were all decent people, their motivations seemed solid.

Things I did not like so much:
This drama could not decide if it was a BL between our two male leads or a reverse-harem between all three leads. The most believable chemistry was between the two male leads and the chemistry between the ML and FL was a bit forced. The ML went from really disliking her to suddenly liking her and she went from crushing on the SML to suddenly falling in love with the ML. As if the script writers and director were suddenly like “oh crap, this is becoming a BL, we’d better put a beard in there STAT!” The storyline kind of fell apart after they left the academy to try and run their respective clans in the pugilistic world. It got draggy and asked one to suspend one’s disbelief A LOT! The FL supposedly had minimal martial arts yet could hold her own against trained killers whenever necessary—but only until the point it was time for a male lead to rescue her. Seriously, were the heroes live-streaming all their actions!? The evil guys ALWAYS knew what they were up to and yet the heroes were always relying on pigeons that magically found their target to matter where they were. And also, everyone could apparently travel huge distances in a couple hours. I get that in a wuxia you have to suspend your disbelief a little—all the flying round & stuff—but there’s a limit. The ending is happy but ambiguous as in the FL never really settles on her choice of male lead.

Should you watch it?
I found it free on YouTube. It’s relatively short. The male leads are easy to look at. The FL is sweet with a good heart and not a complete idiot. It was pretty decent at first and by the time it gets less interesting, you don’t have that much farther to go to get through it.
