They have a "naked in the bath together" scene. It's implied there, though how they act to each other afterwards doesn't make the most sense then.

I thought he was very annoying in Love Between Fairy And Devil, neither good nor bad here (at times continuing his performance from the former), and substantially better in The Princess Royal.

(Spoiler but not spoiler:) Huanyu is internally adopted and treated like a biological son. It's very confusing for a long time.

(Middle-ish spoiler:) Only Shangjue had an actual brother.

The Shang, Jue, Zhi, and Yu lineages are like separate families. So are the back hill families that appear later.

That's what it says below.
And https://kisskh.at/63699-unusual-idol-love pairs them.

I believe they were the only comedy-heavy characters I really enjoyed in this show.

It takes a century and half, one could argue she first goes for every other guy under the sun.

You can perceive it as horrendously draggy. Depends on how much you enjoy the "family stuff" and how you feel about the, uh, different guys that FL hangs out with.

She spends most of the time with two other guys that are various levels of annoying.
There's some quite intense / good scenes with the ML, but enduring what's between those scenes could amount to suffering.

So far only in four SEA countries:

Compared to how it's advertised on MDL ("endlessly fluffy"), the show definitely has parts where it's suddenly unnecessarily angsty.
However, it doesn't stay there for too many episodes, and it (IMO) has some of the better messages of C-dramaland.

Also, there was little filler/padding (to make it 'boring af').

Maybe you should have just watched another two episodes.

What is the connection / similarity?
Do you recommend Love of Nirvana for people who enjoyed this, or ones that did not, and vice versa?

For several episodes, the ML secretly visits the FL under the nose of her "husband". He takes great care not to be spotted by her two loyal attendants. Suddenly, from one scene to the next, he walks past them like it's the most normal thing in the world and he belongs there.

Sort of the Chinese "Rugal":
You won't take your eyes off it.
Nothing makes sense.
Plot holes and production absurdity abounds.

While it's more of a B-tier drama, it feels some budgets are way too big, like the characters changing costume several times a day (in one later episode, it feels they're just trying on ridiculous suits to see if they would work in other shows).

The script is imbalanced as well, with a ballooned up 'palace life/intrigue' section of the show taking up about five times as much time as it should (similarly to in Who Rules The World). At the same time, in that overblown section, an essential scene is missing entirely:

Lately, I only watched wuxia and related shows, so I forgot how pervasive 666 – The Devil's Own Cold Remedy is in modern-day dramas. Here it takes turns with Bestore's bespoke (I'm sure astronomically priced) crispy jujube and generic ("chewy") jerky.

I thought for how fluffy it was, it got unnecessarily angsty/draggy twice. That's the only major downside IMO.

The FL's acting was really good. (As others wrote, ML is not as good at being FL as FL is at being multiple characters. The ML does more of a generic teenage girl.)

IMO way too much time was spent on the triangle, even if it was not really a triangle.

The body switch can't be "real" because of CN censorship.

As a c-drama maker you're not allowed mashing fantasy and reality too much, the present has to be better than the past, reincarnation, transmutation, and so on.
So this is probably the best one can hope for regarding body switching fantasy, and at least better than in various other shows that either do it worse or have the "true ending" in a separate video that wasn't allowed to be broadcast.

After she finds out about Yue Qin harvesting blood from innocent people, his assistant shoots her with some dart to knock her out, and afterwards there's something mumbled about her martial arts abilities being disabled. We never hear anything about them again.

Was unclear to me if it's the dart attack or something they did to her afterwards or her body struggling with the poison or ....

TBH in plot terms it's just an excuse to not leave her as a capable fighter.

Like so many Korean series that claim to feature a crazy violent FL, this one starts dark and interesting, then turns into a slow lengthy standard drama, and eventually just different shapes of bad / boring. It's like any other CGI / green screen show. They have so few ideas of their own that it seems the FL regularly had to tell the director "look, I just did this for The Double a few weeks ago, how about we copy it?".
None of the supporting characters are any interesting, but they have what feels like 40 hours of screen time to pretend to be cute and adorable.

It was really difficult to watch the last third. I'm not even getting into anything to do with the ending. Jeez.

Basically once the 'assassin ravens' disappear for good, this is most of all a waste of time. Watch the first 3-4 eps and then find something else.

(ML's acting is really good. Beyond that most of the cast feels low budget.)

You can start watching the last ep at 44:14 and stop once that segment ends.
