But the way I understand this, the owner of the original body is already dead. Body is also dead of course, that’s why when white haired dude possessed the body, he needs the uke close to him so the body won’t die. But I wonder why if they were really twins from their past lives, why is the white hair dude not reincarnated together with his black haired twin.

Posible that it has to do with the curse. Maybe black hair dude from the past did something to prevent white hair to live. Or maybe he made it that they became one. So that's why the original user was persistent on Kwon, because there is a need for them to be together but it won't stop the original curse.
Or MAYBE JUST MAYBE the original body user was the actual reincarnation of white hair it regain his memories but lied saying he was the black hair one. But because the body is dead white hair insisted on been together.
This is a possibility but as well I can be 100% wrong.

And i’m just saying it here based on how I feel and understand.
Soleite is a dragon. And ‘we’ know Ian and Brian are two different people with the same soul and we may consider them as two different people, but for dragons, they are the same. We humans look at the person but dragons look at them through their soul, and it’s something we humans wouldn’t comprehend.
Gosh, I love them so much. Tbh, I was tired of waiting during the flashback story. But now I could read it again and again.

…but please don’t get mad at me. Can someone please tell me if Ines, in this current life, still loves Emiliano?

It’s better if you read it for yourself. Different readers think different things. The author said in her questions and answers that when Ines saw Emiliano killed right in front her eyes, her love turned to guilt. That’s why she hyperventilates and can’t breathe whenever things with him come up.
Also, when Ines said her perspective in the beginning of the novel, she called herself delusional for thinking her 16 year old self thought she loved a strange man she just met whom she knew nothing about. In this life, before she turned 16 years old, she was still romanticizing her life with Emiliano. Then when she turned 16 and had four nightmare years of punishing herself, the author obviously was trying to portray guilt and Ines literally became afraid of that time.
In the end, the past is still the past. In this life, Ines learns a lot, changes a lot and loves differently. Even the way she talks about love shows she learned about a different kind of love from Carcel that she says changes her.
For Tappytoon novel, I don’t trust much of it so I read the original novel as written by Kim ChaCha. Early on I noticed Tappytoon add things to their translation and removes things from their translation so I recommend readers read the original novel for accurate information.

Here’s the author’s answer to fan question 38 she has posted on her blog:
And the moment Emiliano died at the hands of his brother and she finally killed the child with his own hands, I think all that love, family love, and friendship turned into a terrible sense of guilt.
So love ended then.
The reason she couldn't get out of it and constantly thought about the days she spent with Emiliano wasn't because she still loved him in this life, but it's similar to the accident of a murderer who can't forget his guilt even for a moment.

But could you please remind me why Yoon Jigu thinks Yeowoon likes spanking and tying up?

Bcs when he fist moved in next door, one of Yeowoon's friends who was helping move things was being dumb and calling him "master~" from inside the apartment. Since Jigu was paranoid and already thought he was a stalker pervert, he just also assumed he was into some weird kind of SM play, even complained about it in-game with him

Ines and Emiliano both remembered their past lives. In Emiliano’s case, the one where he and Ines got married and had a child, and Ines remembers everything about her past lives except her very first life where she and Carcel were married, right? Then Carcel only gets to see or remember the past through flashbacks or dreams because he never k1lled himself and he always die an honorable death. Please tell me if I got it right. Or please correct me if I’m wrong.

Basically everyone regresses when they die but the way of death decides if you remember or not. Inez remembers two of her three previous lives because she committed suicide, she doesn’t remember the first because she was probably killed. Carcel is basically forcing himself to remember because of his continuing love for inez and i think the crown prince remembers because he’s a piece of shit.
Let’s say Minchan is really not the reincarnation of Seoho, they’ll put Seoho’s soul into that kid, then Bihwan will be confused because he likes Minchan now but the real Seoho is back now. Just saying.
That kid IS Minchan- he’s showing Bihwan a flashback.
Oh, really? What the helly. But still, just what if. I mean, let’s just say there’s a real reincarnation of Seoho.
