Who the hell was that guy that killed the huge tiger, saved the...princess? I don't even know. Then they got married, and lived happily ever after.

That was only one chapter, but it had the two characters that are in the image for the description of Threads of Time, so it sorta got my attention.

I probably am just confused because I have trouble with Chinese names.

So yeah, can someone tell me, who was that? Was that a chapter about the main character's past parents in their youth?

I've no idea either.

It felt completely out of place and maybe it was about the dead parents? I don't know. 😔

I believe it was the parents

As daddygoat says...it's the parents. It's just a side-story. Doesn't really have anything to do with the progression of the plot.

I thought it was cute though. A kind of comic relief, from all the tension that has been accumulating.

And I believe they are Korean names, not Chinese names. And this is my first Manhwa and I don't watch or listen to a lot of Korean works, so the names are difficult for me as well =P
