Ah, I see what you mean. It’s the inevitable home stretch angst, isn’t it?

The show has an interesting take on time travel. It has only one timeline in which the present (Gwi-ju) is fated to go back to the past (Da-hae) as predicted in the future (Mother Bok), sort of a closed, inevitable loop.

I might not be right and I’m probably doing a poor job explaining. 😅 Let’s see what other Beanies say.

It is presented to us as if Gwi-ju will die when he goes to save her. And probably he can’t not do it, and definitely he WILL do it.
But notice that his mother hasn’t seen him die. She only saw that he “wouldn’t have time” to get out.
Well, first: You know how he disappears, right? He doesn’t really need time, he just stops being there. But apart from that, you know he has been doing all his best to come back and help at that fire, and has just been watching helplessly every time.
BECAUSE Dong-hee wasn’t there to help him! 100 to 1 Da-hae will finally be saved by a cooperating team of back-in-time-travellers, his flying scissor, and his mindreading daughter. And maybe his kind father, and of course those sauna people except scary mum.

Thr rules are:
1)Gwi-ju can only travel back in time.
That means that whatever he does, he has already done. He just doesn’t know until he goes back in time and does it. Or Da-hae can tell him. It can have happened 2 minutes ago, or thirteen years.
2) He can only touch things that has something to do with Da-hae. And only Da-hae can see him. The mirror can’t “see” him, either.
3) He cannot always control when. For a long time, he left all the time, and he couldn’t help it. That’s how he lost his wife.

4) Man-heuk dreams of the future. She has not yet been able to prevent anything that she has dreamt would happen.
5) What she sees is like in a dream; it is not made very clear what is going on.
6) That means that if she dreams a car lay smashed up at the side of the road with you in it, best thing you can do is to smash a car and sit in it a bit. 😉
Her vision will have come true, but you will not be dead.
She draws hastened conclusions. Lottery tickets are simple. But she has interpreted the ring on Da-hae’s finger in three different ways already. She says Gwi-ju will die, but really, she doesn’t know that. And the “not having time” part is nonsense. She has seen the explosion, I guess, and an empty casket at a funeral.
The rules as regards to her dreams is a bit like in some kinds of fan fic, where everything important happens in the scenes between the “official” scenes, but at best so that in glimpses, it fits exactly with the official version.

Aw, shucks!
