Easy. The time line is the same.
Here the thing is that the dragon continues to make the same mistakes and poor little uke die so he repeated time again and again to stay with him. That's why the he was sent to the dream world not to his actual life because in that moment he was supposed to die and not dragon but as we can see it didn't happen (part of what the bull said) and because off this the kingdom entered in a era of loop and finally he was able to survive and we know that no matter wast the uke is always the emperor because one of the town people say his name.
(this are my thoughts of what is happening don't know if am correct but I think is like that)
I sort of get the story- but is there anyone who knows what exactly is happening and what the timeline is? I’m just slightly confused. I absolutely love this story and art- and want to understand it 100% fully.
(Also thank you for another lovely update and hard work, Uploaders!)
