Thank you for taking on this series and seeing it all the way through, much appreciated!
After having a lil time to think, I assume Ah-Zhao was formed from the 'original part', and Tiger the artificial, then? Maybe the events that happened on Ah-Zhao's side, up to the grab through the mirror, where his original childhood etc. Then maybe he got into the accident in his teens which required brain surgery (aka artificial introduced), which is why the friends and getting together with Xiao An were in Tiger's 'universe'? Or maybe it's all jumbled.... Anyway lovely to see he really did end up with Xiao An 'irl', as evidenced by the wedding picture... though not sure for how long they were married since his body doesn't look that old when he perished at the Himalayas
Overall the ending 2 chapters revealed a number of grand sci-fi concepts which did give a rushed feel, but I really enjoyed the journey!!!
