I agree about Bu-Yeon deliberately stepping in for the ritual. But I doubt that they were friends, they were of different houses, Jin clan being especially secluded, and Naksu was taken in by the villains at a very young age. Also, Bu-Yeon probably lost her memories after almost drowning in the lake, she was living with some poor grandma in Sari village for 10 years without trying to contact her family.

But it is in some cases. And also contraceptives are not 100% effective and/or available to all.

Don't talk about it like it's a fact and that it's accepted everywhere.
What about parents who can't provide for their children? Must children suffer in poverty or be abandoned to orphanages with no good life prospects?
What about fetuses that through screening are revealed to be malformed and if born will have severe birth defects, disabilities and high risk of death? Must they and their parents suffer because of it?
What about women who's life is in danger because of the pregnancy gone wrong?
What about women who were raped?

Bu-Yeon is not controlling her. Naksu's actions and inner thoughts are always her own, except brief moments when Bu-Yeon uses her powers to help her or Uk.
The only thing Bu-Yeon could have done, but it's not proven yet, she could have deliberately blocked her magic powers.
Furthermore, it is known that Bu-Yeon as Mu-Deok was a very kind person, so I doubt she'd do anything bad to Naksu, unless she turns evil or smth.

It's a cue for those viewers who still somehow haven't figured out she's Bu-Yeon. But mama Jin is plain blind.

Just look at the poster - that sword is a major plot device. Uk promised Naksu to return her powers so that she can unsheathe it again and use it.

Uk is in love with Naksu, not Jin Bu-Yeon/Mu-Deok.

Yea, maybe that's why mama Jin keeps avoid the topic who was the thief and what was stolen. Maybe the ice stone was kept in the vault illegally and since she used it to give birth to her daughter, she keeps covering up everything.

Uk loves Naksu, not Mu-Deok/Bu-Yeon's body. So Yul has no chances with Naksu in whatever body she will end up.

Ah, ok, you're one of those who has a SML syndrome. Not gonna happen though, since she loves Uk and Uk loves her back. They're not gonna break OTP couple.
Personally, I think he's too much like Park Jin and in danger of being forever alone like him. But he can still get indroduced to some girl.

Why not Yul? Do you want Yul to keep on third wheeling?

I think it's still inside her, yea. Maybe it's even what keeps her alive.

Today's episode was so amateurishly dumb it's like I'm watching someone's bad fanfic. Was this show based on a webtoon? Was that webtoon so dumb as well?

Park Jin's assistant also said "ice stones" plural in recent episode. That was where I first heard it clearly.
And come on, there's gotta be one inside Bu-Yeon as well.

Were you not paying attention? Naksu's dad was murdered because of Uk's birth constellation plate. She's several years older than him.
Yul's age looks to be a plot hole after the three kids scene. He was supposed to be around the same age as Naksu.

No, it was starting to become clear in later episodes with mentions and in the last episode Jin Mu said himself that all the ice stones, plural, were supposed to be destroyed to which master Lee replied that another one appeared.
I'm just wondering, were they split from the original one, or were there actually many to begin with?

Nah, if she weren't that dumb she'd have started suspecting Mu-Deok after she opened the vault from both sides in the mirror episodes and her sight was temporarily lost.
She's just a sad nutcase who's obsessed about her daughter and would do anything to return her.

Yea, that will be a problem. Unless Naksu somehow gets her body back. Then Jin clan can take Bu-Yeon back with no hassle.

Doubt it. Jin clan won't allow it, because he's CP. He a future king, he can't abandon his position and go to Jin clan. Eldest daughter always stays in the clan.
That's actually what Jin Mu said as well and suggested to mama Jin that the second daughter's gotta marry him. She's disposable.

I wonder what his reaction will be when he realizes his filthy Mu-Deok played him big time and is actually wily Naksu.
