Their translation is great, so why are they fucking with the names?

It's what we call on the industry - translator's ego. When a translator does not like the terms and names the previous translator picked, thinking they're not accurate or don't sound good. So they change them when they pick up the translation without any regard to the reader. There are twocamps of translators - one that say it's better to change everything for the sake of accuracy, and another is who prioritize readers and their experience, so they leave the terms as is even if they're innavurate bc that would disturb the reader who is already used to the terms.
Also, Asura's terms and words aren't even accurate, because it should be Erhaben - it's from a german word that means "great, sublime". So Eruhaben was way better than Elfuckinghavenwtf.
And I can't get over "Lark".

Can someone spoil me please...
Who's shiyeon's ex? What did the ex do? What's the story about shiyeon's sponsors? What does his boss know? What is Ose's deal? And Inshu, what does he know?
Currently what is Daejun's position in the gang?

I only know little since I didn't finished the novel.
SPOILER
Sihyeon's ex is the leader of that other group, the one they call tyrant or something. He did some nastyyyy things to Sihyeon, if I remember they were highschool sweethearts and i think shiyeon was supposed to debut first (not sure about this) also about sihyeon's sponsors i think it was his ex too that made him do it. Shiyeon was so head over heels that he'd do anything for him. The boss cares about shiyeon and he knew about the sponsors too that why he want shiyeon to stop. And Inshu, he knew about the sponsors too and once offered shiyeon for help. That's all I know and remembered so far.

Off topic but Im really glad the ML isnt someone from MC's current life
Like I know even Inshu whatever his name was tried to help the og Sihyeon but like the way he goes about it is really arrogant and cocky.
and plus none of these people even tried helping him in actuality, no one bothered to get to know him, helping him in actual sense.
I also need a cute lil big doggo who's so very obedient
