This love is indeed very perilous... but only for the ML. This guy gets stabbed and poisoned so many times that I gave up counting. The way this character is written is a collection of the worst clichés surrounding male leads in historical and xianxia dramas. He is indestructible, will do everything for the FL, except maybe talking to her honestly or confessing his love.
The FL on the other hand is a mixed package. Sometimes she comes across as this gutsy lady who wants to avenge her family, sometimes she is the clever doctor and sometimes she is a meek as a flower and as dumb as a brick.
All the antagonists had at least some decent motivation which sadly isn't a given in C-drama.
The plot of this drama could have been interesting, but the writing was just so-so which on many occasions made the story seem repetitive and indecisive. The acting was pretty good though, which is the reason why I watched it to the end.
In terms of romance this drama offers more than most of the recent high profile dramas as it has quite a few kisses and scenes of intimacy. The chemistry between the couple is really good and at least on the romance side the writers spared us a lot of the usual cliches.
Overall, it is a pleasant short drama to watch as a filler or doing some chores.
