Dramas asiatiques

que si elle n'avait pas modifié son futur et donc celui de la Corée; la Corée actuelle, pendant le laps de temps où elle est absente de sa propre époque, serait devenue Chinoise. Donc, elle est en train de construire son futur et celui que la Corée connaît. Et on peut pousser l'idée plus loin et si c'était elle qui avait introduit l'alphabet Hangeul.

the TIME TRAVEL mystery
Here's my take:

I believe there is a single timeline (and a single ES) -- as per writer Song's admission -- and that single timeline is consistent within itself.
Thus, first of all, ES being kidnapped by CY from the future was always supposed to happen and indeed happened in Faith's timeline, and whatever ES does in the past, she won't change known history, since everything she does in the past would have been part of history all along: ES's actions, decision etc. in Goryeo shaped the very past/history about which a young ES learned in school, in the 20th century. (Novikov self-consistency principle)

So ES's life, chronologically, goes like this:
(1) ES is born in 1979;
(2) ES goes to school and learns Korean history;
(3) ES is kidnapped by CY in 2012; ES is taken to 1351 Goryeo, where she lives and shapes the very history she already knew from school
Under the premise that there is only one timeline and only one ES, CY never died in the trap at the end of episode 16. In Faith's timeline (the only timeline that ever existed, since we have to agree that there are no parallel universes or multiple ESs), ES saw the aged diary pages, learned about the danger, and saved CY's life.
The flashback sequence where she finds an unconscious CY in the teachers' house was always just a nightmare, a by-product of her coma and an expression of her subconscious fear that, without her intervention, CY really would have died. Another clue that the flashback sequence isn't an actual memory from another ES/another timeline: if CY had been killed by the explosion, his body would have been blown to smithereens.

What happens next in ES's chronological life:
(4) ES is forced to return back home to the future (maybe to treat her illness)
(5) because her separation from CY, the love of her life, was involuntary, ES wishes to return to him, but the door between her time and CY's time won't open for another 67 years. That doesn't mean, however, that the door won't be opening between her time and other time periods. Therefore:
(6) ES researches the "time portal - sun flares" correlation, figures out all the time points when the portal opens (and what time periods it connects each time it opens) and writes it down in her violet diary.
Finally, she stocks up on further modern items (ballpoint pen, film case, surgery tools etc.) and goes through the portal again, only this time she travels further back into the past (before CY's lifetime). Since the items she finds in 1351 (the aged diary) are about 100 years old, we can assume that she travels to around 1250.

*It is possible that ES actually travels to more than one past time period -- namely to all those times which had been marked with the yellow marker in the diary. At any rate, cca. 1250 is definitely one crucial time point which she visits.
(7) In 1250 Goryeo, ES becomes Hwata. Yes, Hwata was supposed to have been 1000 years ago, but weren't all those relics (diary, surgery tools) supposed to have belonged to Hwata as well?? Well, the relics are not 1000 years old, only 100. And if they belonged to Hwata when we know that they actually belonged to ES => ES is Hwata.
Oh, and Hwata is remembered as a man because olden time people tended to look down on women, and how could a mere woman have been the legendary surgeon? So history was manipulated to make it seem that Hwata was a man.

(8) In 1250 Goryeo, ES is all alone, desperately missing her beloved CY. She cherishes all her memories with him (from when she was in 1351). She leaves hersef the clues which the younger ES already found in 1351 (the diary, the film case etc.). Having already lived through the events from 1351, she knows when CY was in danger and had to be saved, she knows where to leave herself the film case so that she will find it etc.
(9) In 1250 Goryeo (or some other time in the past which was marked with the yellow marker in the diary), ES waits for the portal to open again. You see, she has already calculated that the portal will open in her current time period (that's why she traveled to that time in the first place) and that it will connect to cca. 1351-1355 Goryeo (during CY's lifetime, after the point she left him when she went back to the future before).
So you remember the animated sequence at the very beginning of "Faith" (episode 1)? When "Hwata" flees the King's men by entering the time portal? Well, that's actually future ES (the sad, gray figure we saw in episode 19) time slipping back to CY.

"It was then that the sun darkened in the sky and the heavens sent down a strong wind. A portal opened up, and Hwata entered it laughing. "....

"We’re in the year 1351, near the Yuan-Goryeo border. ..."An entourage travels in the rain, guarded by warriors on horseback. One guard notices the red light in the sky and wonders, “Hwata?” Seems to be a well-known myth around these parts."

je me suis vraiment dit "c'est fini pour lui"

le méchant avait perdu un peu ses pouvoirs...

qu' il perd son pouvoir de la main...la première fois contre Choi quand celui-ci est venu interrompre le mariage !

encore que je n'ai pas compris que le double dise à Eun So "je suis ton futur " je la vois plutôt comme son passé, mais bon ...

On voit bien qu' elle vient de son futur et non de l' ancien temps...d' aileurs le flacon qu' elle jette sous les rochers est un flacon made in notre temps il est parfaitement possible que la Eun Soo actuelle ait en fait voyagé plus d' une fois dans le passé...

au regard de ce que la "double" a écrit dans les feuillets à "elle-même" en quelque sorte

dans l' Histoire, le reine est tombée enceinte beaucoup plus tard et pas sitôt aprés le mariage...Eun Soo qui connait l' HIstoire s' en étonne d' ailleurs...

Il est plutot dit qu'elle a des fausses couches en fait et que la seule fois où elle mène une grossesse à terme, elle en meurt.
