you're really right, I just think author kinda ruined that romance for me by dragging the first arc too much, like I saw too much of their childhood/growing up together with sibling dynamics so for me personally, I couldn't really see them as romantic partners after that if that makes sense
That is totally fair if you feel that way tbh! We all view their relationship differently. I just wanted to put that comment out here because I saw too many comments being about ew they’re siblings and getting married, so I thought I had to bring a nuanced point of view, so there could be at least one, by explaining how they haven’t viewed each other as siblings at all and aren’t blood related or anything. To me it feels more a childhood friends (and again, given the environment it was more a kind of allies for survival mood) than an actual siblings relationship, they’re not really related, she was reborn in that body and never considered him as her brother and he never considered her as sister either. I found it kinda sad when that story, even if it’s not my favorite, has quite a few nice points to it. I guess it’s okay as long as we don’t get judgmental of other people’s taste and try to police what they like, especially given that this work is not incest.
I have to say, I’m the first to usually drop stories when it’s siblings romance as end game, but this doesn’t feel like it for several reasons. The two of them are never really raised as siblings, it’s more of a them against the world if anything. The environnement in which they grow is everything but familial and they are here for each other but it’s never really family affection, due to the particularity of their environment. Dietrich never sees her as his little sister, he sees her first as someone intriguing, weird, then as someone precious, who becomes his only weakness, the only person that can actually understand him, after a life of loneliness, danger and constant wariness, where he had no one by his side.
Anissa, as someone who has been reincarnated, never really sees Dietrich as his brother either. She rather sees him for who he is, someone who has been mistreated, who never has received love properly, she’s horrified at it. Later she’s frustrated at how he’s been treated, he’s doing the right things, yet he’s seen as a villain. She first holds onto him like a lifeline. So the complain you could have about it is that she first sees this relationship as more of a way of survival, rather than an actual sibling or anything relationship.
To add to this, the two of them are not related at all. They’re not siblings, they don’t share a single drop of blood together.
Of course, I won’t tell you what you should do or not, but as someone who is usually disgusted at sibling romance trope and who wasn’t much disturbed by this one, I’d say you should probably read the story first and see how it makes you feel, rather than just judging it by the way people talk about it.
