I amaze with the plots, it was very mind blowing however the execution was lacking. They said after the travel door is closed everything will be reset and all travelers will disappear. But WHY Gin Gyeom was alive in the last episode? Isn’t he supposed to not alive? Since his mother was a traveler - meaning she would have disapear and not giving birth of him? Aside from that, WHY it seems that Tae Yi 2020 and Gin Gyeom 2020 was falling in love? Aren’t they supposed to have mother-son relationship? Well this is confusing... I need explanation from the producer :(
In my personal opinion there’s no way they can build relationship more than mother and son. I prefer Gin Gyeom to be with Do Yeon cause it is more logical.
