I wasn't even going to watch this because 37 episodes of just "bromance" and "censorship" didn't sit right in my head...But Oh Boy! oh was i wrong and about to miss out on a masterpiece.
Just the aesthetic of the outfits, set, décorations, houses...and tools used to present that era of time...Goddaaaamn
I can spend a whole hour talking about how well done and accurate the representation was, each outfit and location would spun me.
(Spoilers ahead)

As for the story, it starts out very strong, the first episode took me so long to follow up with events because too much happening at once, almost all main characters are being introduced and the first piece of the puzzle is being laid down...fast forward few episodes, you start to appreciate the dynamic between the two leads, understanding their goals and loving their cooperations and that lasts throughout the whole series.
It's more than a bromance, you can sens the soul mate vibes between them, each one is the other's lifeline.
The story is amazing, the plot line is something new and never seen before.
Also It is not a very happy, cheery and joyful type of series so do not expect to be laughing all time but the few funny moments there is, they're impeccable.
I hated the ending, not gonna lie, i was heartbroken more than once over the loss of so many great characters but i was ok with it...but the ending just F***ed me up man.
I know there's an alternative ending, so i very much encouage everyone to check it out.
I highly recomand this series, totally worth the emotions and time.
