I have a question how in the sad ending world Yi Xun knows about the letter thing and still wait for the letter…
So I think the ‘sad ending world’ is actually not even the original world. The original one wouldn’t have had time travel and letters involved. The first action which causes this chain of events is older Xun sending a letter ( remember he says he’s waiting to send a letter not that he’s waiting to receive one).
The catalyst for the truth about the mum is from meeting Shen ‘the bully’s’ Dad. Which answers some of Tang’s qs. This is probably consistent with the originally shown timeline because she has burns.
Since in the sad world she finally gets a response from her father before the dual suicide we can assume that in that original beach scene perhaps the hairpin doesn’t fall and the body is on the boat prior to Tang arriving so she is unaware he is disposing of the body +/- evidence. We also don’t know what time Xun would have arrived at the beach because he turns himself in implying the interaction about calling the police never happened. He may not have been stopped by the cat or the letter didn’t arrive in time, letter was never sent etc etc
One possible outcome could have been that they pushed the boat into the water unmanned and the crazy currents took it far away before Tang could see what was in the boat but I’m sure you can think up thousands of different variations.
All in all, there are probably many more timelines than the ones we are privy to. I discussed a theory about this in a newer comment. We’re only seeing snippets of two timelines (maybe three) but it follows the idea of a multiverse theory.
To succinctly answer your question, we will never know! But perhaps some of the things I mentioned can give possible answers. The older Xun with ‘dementia’ (see my other comment) may be the only one in this universe with all the answers but he took them to the grave.
Did anyone else question whether he (Xun) has dementia or if it might perhaps be sequelae as a result of having knowledge of several timelines?
It occurred to me in the first letter he mentioned about ‘trying several times’ but making things worse.
He’s also the only one who has used both mailboxes and in one of the later episodes ‘episode 11?’ He’s muttering in a daze about how the mailbox can’t be demolished.
I wonder if we’re seeing one of many (100s or 1000s) of potential timelines. This was just one that had the best outcome.
Interesting to think about how things may have gone devastatingly wrong with a slight change. I wonder if older Xun started having these symptoms after coming into contact with ‘the/a’ mailbox at the dock.
Did they ever explain how Tang Yixun's finger prints got in Ye Haitang's car in 2026?
The fingerprints they’re referring to are from his house. They were trying to confirm his identity. I nearly made the same mistake but if you re-watch they mention dusting the home.
