I don’t have Crunchyroll,

You can watch it on youtube! The animation's great however there are parts of the og manhwa that were adjusted to suit general audiences.

But the entire story was perfect. What did they adjust?

I'm pretty sure that they followed the novel's story more than the manhwa's storyline as spoon did change some stuff; also, the animated series is from Claude's pov rather than Annette's based from what I've seen but I have yet to watch the whole series so...¯_(ツ)_/¯

*Athanasia's (My brain wasn't working and accidentally combined Athy's name and Jennette's name (~ToT)~)

i personally dont plan to watch all the episodes since i dont like the art the animation is ok i think but it doesnt look like the manhwa at all so im out. plus, the reason why there are changes is because its a chinese animation and alot of stuff in the story is either considered taboo or too graphic/violent for children

was current-timeline Athy being a reincarnated south korean Spoon's idea, too? I've never touched the novel version, but I did watch the available four episodes of the donghua—and that bit felt like a big change for me, cuz I ship lucathy ( ；∀；)
