Loved this show, albeit the last few episodes are obviously rushed and the director has inserted many technicality to explain the logic of time travel. But, the actors act naturally and this genre is fun to watch. Anyway, as a diehard fan of time-travel series, here's some explanation about the timeline!
This is an explanation for the timeline, 1. Original timeline - old phone exists, Ye You Ning (YYN) underwent his high school and university without having a meaningful connection with Xia Wen Xi (XWX). At the beginning of the show, in a future time period (2019), XWX met YYN at a talk but they don't really know each other (although the emotions of XWX are kinda confusing, but well). Accidentally, YYN found that the old phone (time machine) of XWX is capable to do time travel and he intended to go back in time to save his grandpa - but unexpectedly, his journey entwined and changed both YYN and XWX's life forever in the original timeline. With every amendment he done has led to increasingly worse outcomes, YYN has ultimately decided to go back to 2006 of this timeline and forcibly separate himself from XWX. However, every fixation of the timeline has created multiple images of memory (from different parallel universes) in both YYN and XWX's minds. Fast forward to 2019 again, XWX is suffering from uncontrollable memory surges and this led her to investigate deeper. Lastly, XWX has managed to find YYN in this timeline. They both destroyed the time machine and they were then erased by the universe - as they were not meant to be together in this timeline, the universe has its own law. 2. New timeline - old phone is gone, As the universe restarts again, in this new timeline, everything seemingly reverts to normal. However, something is different this time. Back in 2006 of this timeline, the phone is gone. Will YYN and XWX become strangers just like how they were before in the original timeline? The answer is apparently not. With the existence of unexplainable images of memory from the parallel universes, XWX still remembers YYN is scared of the bursting of balloons eventhough they haven't even introduced themselves yet. Fast forward to 2019, here we are at the beginning of Ep1 again. But this time around, YYN no longer looks at XWX with a cold expression. From his eyes, it is clear that YYN has long known XWX. The episode ends with XWX patiently waits for YYN to finish his talk, signalling that they are already a couple in this new timeline without the time machine.
In the timeline with time machine, YYN will not meet XWX. If YYN forcibly uses time machine to connect with XWX, the universe will punish them and constructs a bad ending for them. However, the happy ending will only come once YYN and XWX have understood that their intention of altering the timeline using time machine is wrong in the first place. Perhaps, the time machine is created for the time travellers to learn about the true meaning of to love and to cherish your loved one.
