wtf then its means she ends up alone in the end
All male characters that sympathize/blush/like Fia are baits or pseudo love interest. NO ONE "romantically" crush/like/love Fia. No one. Friendship, respect and loyalty, yes. But love, nope.
She ends up alone because no one romantically pursue her. Fia doesn't fall for anyone. The dark haired knight/comander (I don't remember) that's been with her and are smitten by her, marry one of the mediocre pseudo saints for obligations which is sad. The novel rewrite off as "it's ok, maybe he'll for the saint bc married in loveless marriage". Reincarnated knight is devoted to her person because of loyalty. The other knight doesn't love her and confessed any romantic feelings towards Fia WHICH BEGS the question why the manga insist of drawing him and Fia in moving romantic scene of them staring at each other eyes. Baits. All baits for romance thirsty readers. Fia is very much written off as a prima Donna protag that doesn't need romance or a love interest because even if the guys don't love her they're devoted/trust her?????
People have been calling this serie cliché and the protag being too op bc her familiar is a dragon. But honestly let's get serious pretty much all fantasy isekai series are build on this cliché: mc IS op, is THE FAV of SOMETHING, dark magic/spirits/everyone, has knowledge of every single recipe down to how to make every single ingredient (grain, shampoo, chemicals etc)...
The presence of one cliché in more than one story doesn't mean that the rest of the story is the same in all manga/webtoon this cliché happens. Isekai itself is a cliché. But we. Never get tired of it because it's different every single time.
As for the spoilers.

From the manga adaptation too. Seems like the author like to go back and forth changing details that was established earlier. Idk I feel like the author doesn't have a clear idea while writing but just keep adding. And also a bit all over the place... So I'm not getting the story is slowly unfolding vibe. It's not necessarily bad ofc. Since its still enjoyable.
Ok, spoiler:
The story has no Love interest. I don't feel like calling this manga a shoujo... It's fantasy thou. But the author loves to shit tease. Like dropping a male character saying he's interested in Fia but later on set that guy to marry/end with someone else. I say "that" character but there's more unfortune men ending up marrying for political reasons... Wasn't even love more like they just gave up and accepted being married to some saints (that are ofc all closed minded, prideful and stuckup). Which is actually depressing. Even more with Fia congratulating them for their loveless marriage. Like girl... (￣ε(#￣)Σ
The brothers that betrayed her in her prev life,... after her death, it was implied that f get were likely either killed or outcasted by her knight ( latest chapter hot stud) who sized power and become emperor.
