Ahead

ML is only used for one true pair who truly love each other.
MC is for any character that is important for the story.
Yul is not a threat to Uk.

I don't think Naksu is that cruel even to the point to use Yul's love. She doesn't crush on people sincere love imo.

Uk is only a human. He can feel depressed after getting sincere confessions as a poison and thinking he was the only one who miss her. He felt embarrassed too. MD giving away the jade was a big blow to him. He is only 20 years old and has found his love so he can be emotional. Any age would be emotional at this point.
Give him a break. He will train harder when he is motivated. 😅😂

True. I feel that Yul and Dang gu are not a strong mages; worse for Cho Yeon.

But the main leads can't grow fast cos many characters who are in power are blocking their way. So, they are being conscious. The writers wanted to introduce more stories from other characters and wanted to explain more background stories. So, the pace is slower than before but I can't blame it as a filler. But I will blame for leaving us on a cliffhanger. Cliffhanger started from ep 9 I think.

Can't wait. 🤩

But like most k-drama FL, no matter how 2nd ML treats FL well, FL only like the one who she likes. So, I am already feeling sad for Master Lee cos the looks in the Kim's eyes are different when she looks at Park Jin.
But let's see how it goes cos there are still 19 episodes left including part 2.

Great analysis on CP and Naksu parallel journey.

EP 11' preview is lit!
MD, "Do not go to your room and just stay here."
They are going to be reunited tmr and the next arc is coming.
EP 12 is going to be epic! 🤩😎😉😆

CP said that at the expense of my gold toads, Uk is getting duelled with Jeongjigank's mages every day.
"Did I get fooled by filthy Mu-deok?"
What a funny guy. I love his reaction. 🤔😅😁😂🤣

Bu-Yeon was born the same day as Uk cos of ice stone and cos she was already dead.
Uk did bear on the king's star night but his birth was by soul shifting.
That's what ep 11 means about Uk right?
If anyone has a better explanation, pls do. Thanks.

Funeral? What! No. Send the rest. 😅🤣🤣

MD, "Here is your antidote." 🤩🤣🤣🤣
She almost nailed it but "sorry" ruined it. 😅

Uk should have figured out by what MD had said though.
MD said, "Just as you saw my blue mark and found out I was a soul shifter, you have once again caught me. You have found another weakness of mine."
Instead, Uk dwelled on poison and negative thoughts given by Dang Gu. But he said that he will complain. XD (I like that part though.)
Can't blame Ukie either cos she turned his sincere confession into poison. And he thought he was the only one who missed her. Can you imagine how embarrassing it must be? 🤣🤣🤣🤣🤣
Hong sisters have a way to twist straight confessions. 🤣🤣🤣

Park Dang gu to Park Jin:
'No one?'
'Not once?'
🤣🤣🤣🤣🤣

There were flashbacks but they never show the whole flashback of how ML's family got killed and why FL was there. I know that she was there to stop the curse but they could have explained the story better instead of making us think by ourselves or filling ep 5-15 with fillers. I love a happy ending but this story shouldn't get a happy ending at all. They should have let all the main casts die especially the main leads.
The cause of the main problem was cos of FL. She left him without giving a reason that she would be back. Then, a sister and brother kept quiet about who killed the general's son. General getting revenge just based on his ill son's words. Then, killing the boy who tries to kill ML.
In short, revenge revenge revenge and karma and evil humans. ML's mistake is instead of rescuing FL and leaving, he killed them cos he was angry with how they tried to kill FL knowing that she won't die.
Also, they never explained FL's sudden surge of power in this current life.

Edited:
Some grammar. XD
ML winning against all the monsters while he was human or even after he became Bulgasal doesn't make sense. There were no training scenes. He fought just like any elite fighter would; nothing special. He was not evening using his power well. I am disappointed with how he fought all the monsters.

You only need to watch episodes 1-4 & 16 to understand the whole story. 🤣🤣🤣
Not just this drama but most dramas kept portraying bad humans.
The pacing was so slow and I felt that the writers looked down on the viewer's logic too.
But I kept on skipping and watching to see how bad it will get. 😅😂🤣🤣
More in the spoiler.

But Seo Yul loves Naksu; not Bu-yeon/Mu Deok.
Crazy theory from Seo Yul's stans. 😂

True. I want four seasons to accept CP too. CP is lonely. XD

🤣🤣🤣
But Park Jin said that he would still locked her behind Jinyowon door but his heart would be broken.
How long will he be obstinate? Come on Park Jin! DoJu is your last chance in this life. XD
