It's Joy of Life, but a bit different. There, that's the review.
It has all the cool actors from JoL, it has the same approach to humour, the characters are nice and the story is competent if a bit predictable.
In my JoL review I wrote:
"Put simply - the show is all about intrigue and plots, with a side of romance and mystery.
Trouble with this - the intrigue is not very clever or engaging, character motivations are shallow or terribly overcomplicated.
....
I wanna watch Fan Xian and his brother run a book shop, or do poetry battles and flirt with pretty ladies. I don't care who his parents were, or what the two princes are secretly plotting."

MHH improves on this, somewhat. There's no mystery and the annoying courtly intrigue only takes over about half way into the drama. Before that we do get the fun characters doing fun things. And yeah, the second half is suddenly about "Serious Matters" and I immediately liked it a lot less.
The main couple has great chemistry and I loved seeing them together.
The show leans heavily into the girlboss thing, but it's more lip service than the plot actually reflecting that girls can do it too. Like there's a whole huge chunk where the wife is not even present (because we need space for another love interest, which is the same thing I complained about in JoL). And in many other episodes she doesn't really do anything clever or competent, she's just there.

It's fine. It's ok to binge and skip the boring parts. It's fun to watch the many wife guys be cute and a bit useless, it's cute to see the main wife guy's dynamic with his cool wife.
The story I could not care less about. Of course there's a big "twist" at the end, because this is Joy of Life But Different (tm). Whatever.
