Sooyi

I haven't actually watched the drama yet, I just got a basic grasp of the storyline and characters through recaps. So do they mention later on why Yoojin and Kijoon got married? I expected they'd still stay together following the discovery of their tryst, but I'm genuinely stunned by their marital commitment, well unless they're expecting.

Maybe it's too early to say this, but I get the feeling this series is well-written. The writer doesn't rely too much on dramatic elements or twists, and I don't see filler scenes. Characters exist for a reason, and are their own person (I especially liked how the writer developed Woojoo's character--she showed that he just stepped into the professional world with his mannerisms). Perhaps it'll be just one instance, but I appreciate how the writer also shows the side of the victims and their families, unlike most police procedurals. In addition, "Through the Darkness" criticizes the way the media tends to report these cases: more focus is given to the offender than the victim, and the victim's memory is often disturbed for the sake of sensationalist journalism.

Episode 3 has comedic moments, but they don't involve KNG.

This was an interesting read! Oh yes Kang Dongwon was breathtaking in "The Duelist". Did you see "Kundo: Age of the Rampant" too? He also has a magical hair moment there.

To answer your questions about male hairstyling in costume dramas:
-From the mythology and culture I've learned through xianxia dramas, white hair signify advanced age and an extremely high level of cultivation (but Donghua from "Eternal Love" was born with white hair---I think it was a visual choice to highlight his "otherness" because he is neither a god or a demon).
-In my opinion, bodyguards have loose hair to visually highlight their lower social status from the noble/royal they're protecting. Also, I interpret it as showing their job is more "relaxed" and has more movement than the confines of bureaucracy.
-This is more of a narrative device: villains have bangs and long curtains of hair to show that they're shifty people, they're hiding schemes right under people's noses :)

Another thing I realized about Asian historical dramas is that villains (or characters who've gone bad) usually sport mad eye make-up lol

So I was wondering why K mostly wears white tank tops with Hawaiian shirts? Nothing wrong about that, but his style seems retro. Then it reminded me of the clothes Jung Woosung's character wore in "City of the Rising Sun". So it's plausible K came in existence in the '90s.

According to Sooyeol's character profile on the drama's website, he was found by Dongyeol 20 years ago, and then he collapsed and woke up with no memory of who he is. I guess he was part of a big conspiracy, and K is the product of Sooyeol's trauma. This leads me to think the same evil that terrorized young Sooyeol has reemerged, thus leading to K's awakening.

The premise is interesting, but the execution feels like it's lacking something.

The setting reminds me more of the story "Shui-mang Plant" by Pu Songlig. It's an old horror tale about a man who was lured to drink a tea brewed from a poisonous plant, the shuimang, by a girl who needed his soul to reincarnate. People who have consumed the shuimang can only be reborn through taking the soul of others who have taken it as well. However, the man couldn't neglect his duty as a son (in Asian culture, you have to take care of your parents in old age), so he came back to the world of the living. He managed to track down the girl's incarnation, and brought her soul with him.

At first, I thought Sangwoon had the misfortune getting entangled in the female bulgasal's fate by being born her twin, but then why would the monster be attracted to her, and not Sangyeon. Additionally, Sangwoon's the one who can feel the monster's presence.
It seems obvious now that Hwal had history with the female bulgasal, but he doesn't know himself and her, unlike her who remembers all her past lives.

It's funny because I also imagined Lin Yi in the role of Habaek/Hebo :)
I have always wondered why Chinese production companies have never thought of turning "Bride of Habaek" into a live action series, considering that they have the budget, time, resources and technology to do so. Plus, as you have mentioned, the mythology has roots in Chinese culture, and the characters are technically Chinese, so the premise wouldn't be foreign.

The novel says that she mysteriously died from measles like her first child, the Crown Prince. It's inferred that she, along with her son, might have been victims of a scheme.

It looks like the drama adaptation is going to deviate from the novel's plot a lot because from the novel spoilers, Deokim became a court lady to financially support her brother's studies to become a government official, whereas in the drama adaptation, she entered the Palace to buy a noble title for her brother, who was forced to leave the capital for being the son of a traitor.

They better keep "Lost You Forever" as the official English title. "Sauvignon Blanc' makes it sound as if's a modern drama set in a vineyard. Really I thought the English titles were getting better, and now this.

Exactly, if Park Hae-eun's a rookie, then she obviously went through an audition process. I feel like she didn't quit voluntarily.

I understand your annoyance with the character but you shouldn't criticize the actress's appearance.

I know Prince Zhou's a royal and all but he's doing EXACTLY Fu Rou doesn't like in a person, somebody who uses their lofty position to get what they want. I feel very uncomfortable when I see him with Fu Rou.

Not only does Jiah and Inbeom's respective color palette reflect their personality, it also indicates their roles as the Black and White Impermanence, I believe. They're reapers who escort souls to the afterlife.
Also, I think Inbeom is of exorcist lineage like Jiah because he absorbs the memories of the ghosts as Jiah does after expelling them.

Episode 4's ending was unexpected. Was this why President Do said he's not afraid of ghosts?

I tuned into "Sell Your Haunted House" for the dark setting (I thought it would be more comedic like "Hwayugi"), a different portrayal of exorcism and Jang Nara but yes Jung Yonghwa didn't disappoint. He does give humanity to a character who lives for himself and is rather grey in the legal area. Also he pulls off the possession scenes really well, especially when his body got taken over by the ghost painter.

I had the same idea. Here reversely, the male lead is the expressive one and is prone to create trouble, and so far it's the female lead who comes to rescue him.
