I’ll give you a little tidbit, this is a spin off of another manga and takes place years before this one, the two main characters here are in the other manga, neither of them die, just get major religious guilt and trauma and there is death, just not Arsenio and Sauro, or the parents, just make sure you also read “The Witch’s Servant and The Demon Lord’s Horns” to see the happy ending because this manga does end in tragedy

and here’s the link to the other manga

Can anyone give me a spoiler? Like will someone die? Or will they part ways? Etc... I wanna read this but the comments make me think otherwise and I'm not really into angst and tragedy ㅠㅠㅠㅠ
