• I still remember that easter egg in the first episode wherein "Luna" in the rabbit suit runs to the forest, and there was also a clue where the case of the sword was shown as empty. Lady Noh was also seen several times contemplatively staring at it. I think the sword will have some role in maintaining the balance of the two worlds. 
• Why is Nari's hair still long? Didn't a previous episode show that she cut her hair short? This is also another aspect that's boggling me.
• The clock on the drama's logo had always been moving counter-clockwise. Now in the preview for EP14, it started to tick clockwise. Is this another easter egg? 🥚

• One year after the treason, Lee Lim sent his doppelganger corpse to KoC.
• Here's one favorite quote from this episode (I wasn't able to note who said it): "Sometimes life flows in unexpected directions."
• I wonder why the drama is titled "Eternal Monarch"? Will the king become immortal? Will he be trapped in a time so in some way we could say he lives forever?
• Poor Jangmi was puking at the roommate crime scene. So this was his first time to see a dead body killed. Ahh I really think you should have a strong mental health if you want to be a police for a long time.
• It was mentioned that pink lotus flowers represent trust.
• Nari gets a haircut. This aspect of the story really got me confused because in later episodes she is shown with long hair again. 
• I liked Nari's statement about the balance of the worlds. "If there's more than one of something when there's supposed to be just one, it will cause chaos."
• I'm starting to notice that there's a recurrent play of the effects of reflections. There were several scenes wherein the angle shows a character's reflection, or the mirror was just in the background. I think it's a subtle reference to the parallel worlds and of their doppelgangers, which is an effect I really liked.
• All these events between the parallel worlds are like movements in a game of chess. LL and LG have the position of king at their respective sides, and the doppelgangers advance and kill their counterparts, like a checkmate move on the chessboard.
• I found it really funny when Jo Eunsup fainted when Jo Yeong said it is not compulsory to do military service in his world. 
• I found it cute that the phone JTE gave to LG has a sliver horse phone case.
• Lee Lim said, "I always do everything in advance." Is this another hint? 👀
• I find that hospital head so suspicious. It was just a few-second scene but I already hate her. LOL.

• JY and JE suddenly had this split-second connection, wherein the doppelganger felt the other person's senses and they became momentarily confused because JY was supposed to hold a coffee mug, but it felt cold, meanwhile JE was about to hold the milk tea cup, but instead felt that it was hot. As of this writing, we are now in the last episode and I think this scene was still not being explained.
• LG says "Every moment of my life is history here in the kingdom of Corea, and I want that to last forever." LL also said something about rewriting history, and I think both of them are using their own metaphor, with history as the theme, with regards to their true aspirations in life.
• Lady Noh says to the king "What will I do if you travel so far away?". Oh madam, if you only knew how far he'll travel (well apparently she knew from the start, huh?).
• LG purposely placed the book inside the jacket pocket so that Lady Noh would be able to find it (book goes to bedroom, the rest of the things to the study). Later on it was revealed that this move was intentional and the book was a gift to Lady Noh.
• During the general's (?) father's funeral, who is that guy that was focused for a few seconds behind JY? Was it just an artistic camera pan? Am I just over analyzing everything? 
• Isn't this the funeral wherein LL was spotted in the CCTV? Is this connected with my observation above? With LL, you'll never really know who he'll end up recruiting to his gang.
• I initially thought the church where the funeral was being held is the Myeongdong Cathedral. Well it did look similar, but it's a different church (I think it was located in Busan).
• Why did LG have flashbacks about his neck injury after attending the funeral? I am writing this with only one episode left to air. I just thought of this theory -- it's very noticeable that LG's neck injury is at his right side when clearly on the night of the treason LL cut his neck on his left side. Maybe this is related to the rewriting of timeline that would occur as LG travels back for the second time. When LG sees LL strike his young self with the flute (or another object assuming the flute remains whole) at his left side, this will be his realization that this is the timeline that he should keep. You know what, with this drama, possible theories could be endless!
• I really love the attention details of this drama. During the scene when JTE and LG were in the library, there was this one shot wherein JTE and LG were being shown facing each other. On the second floor, a lady is walking from JTE's side to LG's side... but then as she continued walking across, she did not appear on the other side of the library at LG's side. It's a subtle detail that shows that JTE and LG are in the same library but in different worlds.
• I have noticed that identity is such a recurring theme in the drama. Notice how the mood of a scene changes when someone presents their ID to the people around them? This scenario is mostly shown whenever the police team has an entrapment operation or they are interrogating someone. It's also a powerful symbolism because well it was all because of an ID that LG had the connection with JTE, which instigated their love story.
• When LL arrived to RoK, he adjusted his golden pocket clock to an hour forward. This is a subtle detail of the time difference that happens inside the portal.
• With regards to the recording of the news that JTE found on the 2G phone, I had this theory that the worlds of RoK and KoC are running in a different time with each other. The news recording mentioned about Professor Lee Jong-In attending a conference abroad. In KoC, he was indeed in a conference. But the 2G phone has been discovered for weeks, so I thought there was also a time difference between the two worlds. Well we've reached episode 15, and apparently this is not a correct assumption (yes I was just overthinking every little detail of this drama).

• How could LG leave the flute the first time he and JTE went to the bamboo forest? That item is so precious I couldn't believe he left it somewhere.
  
• What's the significance of that glass-breaking effect we see whenever the portal gets opened?
• Who is Kim So Wol?
• I liked JTE's statement to KSJ when she was teaching her taekwando: "You'll fall several times, but I will teach you how to fall safely." Aaah JTE, if only you knew!
•  Maximus is such a good trained horse. I believe the staff (or the trainer) were doing cues for her whenever she needs to act a certain way for a scene.
• Did you notice that scene transition from KSJ's face and then to his KoC mother? At this point, the connection between them is still not being revealed. That's one sly move director!
• I liked how Lady Noh praised Seung-A on her fan fiction stories. 😆
• PM Koo was addressing her cabinet members with her hands folded. I found this gesture a bit weird, because here you are trying to convey a message to your party but your body language is "closed."
• I found it disturbing that officer Park Moon-Sik was just mindlessly drying his toothbrush on his way from the comfort room. LOL.
• KSJ's family went bankrupt when he was 15. I wonder what happened then?
• That long bridge became one of my landmarks to know on which world a scene is taking place. I still get confused sometimes.
• We see KSJ's KoC mom always frequenting the bookstore. So she was the one inserting those notes inside the book to pass messages to LL! I did not notice that!
• We also see here in this episode the umbrella (with the flute) that LL left at PM Koo's mother's place. The foreshadowing is real on this one.
• It was also mentioned that the flute is both the key and the lock of the portal between the two parallel worlds.
• I really think the theme of the poems that Lady Noh was reciting is the destiny of JTE and LG's relationship. Huhu.
• On my second watch, I still found Lee Minho's character very irritating. The "I am King" attitude is just exhausting. Good thinkg JTE was able to endure it.
