Ahead

This song is to calm you down though you shouldn't be listening with full blast.
It may help you to fall asleep. XD

I don't think MDL has a full list. I clicked Explore>Top Shows>https://kisskh.at/49231-move-to-heaven
But in that drama's page it is ranked #4.
You might want to ask a support to get better answer than mine.

True. Also, I am learning new abbreviations thanks to you. 😅😄

[환혼 OST Part 3] 정세운 (JEONG SEWOON) - 바라만 본다 (Just Watching You) MV
If you don't like this ost, I give up. ¯\_(ツ)_/¯

Here are a few more points on why I stick to 2 souls+one body (MD).

8. Bu-Yeon was still a baby when Naksu’s dad was killed. JBY got lost in the river after 10 years. They both don’t have blue marks*.

9. The soul is the one that carries energy/divine power. That’s why the old man did AoS and still got his energy fine. Master Lee still got his energy even after going into the dead little boy. If JBY did AoS on anyone, they would go blind automatically cos of her divine power.

10. This is kind of cheating cos this will be based on a rumour of part 2. Naksu’s soul will return to her original body. JBY will be left with MD.

@nosnoop said, “The Korean title 환혼 (Hwanhon) literally means Return of the Soul; but it should mean more like Resurrection in this context. But if you just put it in Google Translate, it would give different translation as it can mean different things in different context.”

“Resurrection?” – Resurrect Naksu’s body?

"making the king star with socery"
I believe that Jang Gang only used AoS with the late king. He didn't use the ice stone to let Uk born on the King's star day.
EP 4
Start – The late king talks about divination. Jang Gang hoped that there would be no King’s star on that day but it did which means he didn’t use the ice stone to force Uk to be born on that day. (Park Jin misunderstood that and thought Uk was born on the King’s star day through sorcery. Sorcery was used for soul-shifting only.)
Sorry for the late reply. I went and re-watch it again to find out more about Jang Gang.
Jang Gang compilation:
EP 1
Start-12 minutes
EP 2
Start-3:40
EP 3
Start-2:33
19:41 – When the body is so weak, you might not be able to use energy.
1:07:04 – He is the king’s son; Jang Gang admitted.
EP 5
34 – Constellation plate.

Times MD went to Jin’s family:
Near the end of EP 6 (Mirror event).
47:34 of EP 15 (MD was asking Cho Yeon as her witness.)
What! Only 2 times? Well, MD did say that she was afraid of JHG for no reason.

I re-watched AoS to understand Jang Gang better.
If you are interested, you can re-watch just his parts.

EP 4
Start – The late king talks about divination. Jang Gang hoped that there would be no King’s star on the day Jang Uk would bear but it did which means he didn’t use the ice stone to force Uk to be born on that day. (Park Jin misunderstood that Jang Gang used ice stone to force Uk to be born on the King’s star day through sorcery. He might also think that the late king forced JG to use sorcery. Sorcery was used for soul-shifting only IMO.
True. The sorcery was still involved but I would separate, "making a baby" and "giving birth on that day" as different things. )

When UkiDokie came out after shattering the mirror, the door turn bright and the light shone.
Look at JHG and Cho Yeon's reaction. 😂😋
There were very surprised at how the door opened. They know that only they can open it & how did the door open! 😅

"she has met jang gang and he has told her what to do. "
Yup. Jang Gang might have saved her and let her meet Naksu on purpose.
But why did he leave for 20 years if her is going to help Uk?
Let's wait and see.

I believe in two souls and one body so far cos:
1. There were no blue marks on both bodies (Naksu and MD) in the first place. Naksu only gets a blue mark after using the soul ejector which means it's her first time using AoS.
2. Naksu's body didn't wake up like Gil-ju after AoS. Even the blind girl will wake up and say something. But this body didn't move at all.
3. When they did AoS for the first time, their souls look like their bodies' images.
4. Two personas would look the same but they were not.
5. There was one time when Naksu looks like blindfolded MD in her dream, but I think it was because the soul was moulding into the body's image or she could go wild. Maybe.
6. If two personas, why was the blindfolded girl (JBY) so generous & kind to Naksu just as So-i said. She literally let Naksu take control of MD's body. She didn't come out when MD's got tortured for poisoning Uk.
7. If there are two personas, why didn't the blindfolded girl try to take control? If we are talking about souls, JBY's soul knows that she can control the body at any time and let Naksu control her for now.

gtg. See ya.

Thanks for your explanation & worry about my mental health. XD
It just came to my mind so I just post it as a theory.
I usually don't speculate too much on the title cos most title doesn't match the story. But I sometimes like to wonder. 😅

Thanks. I can't remember who posted it. 😅
She/he will eventually reveal themselves.

The Title: “Return”
Theories based on the title.
Which one is it interpreting or is it all?
Returning all the ice stones to the sky is the main point of the story.
Naksu’s soul returns to her original body.
JBY returns to her rightful place.
Everyone returns to their rightful places.
Everything is back in order with the nature of the law.

Must Read This Twitter post. She explained it so well. I have been wanting to explain too but I was lazy and I don't think I can explain well as good as her.
Someone (Is it @Vniverse?) already shared this post, which is very good too.
I will just repost it.

😅😂
It could be.

The eyes. You just can't help but fall in love. 😆

Yes. I remembered 2nd point as one. Now that you mentioned it could be two times JBY was active.
I want to know why MD put the blindfold too. She knew that JHG hate her after the mirror got broken so why?

My point is to remember how many times JBY saved them. Then, she became inactive again.
I will change the title to "Numbers of times JBY was active". Then, we may figure out why JBY is active for sometime only.

Numbers of times JBY was active:
MD jumped off the cliff into the lake to die.
MD almost got killed by Master Lee.
JBY saved Uk from soul-shifting.
JBY saved MD from the mirror.
JBY saved MD from soul-shifter.

Is there more? Pls, comment if there is. Thanks. 😅

Numbers of events JBY saved UkieDokie >>> Numbers of times JBY was active
