The significance could be that it represents a unique sad story in an English - related context. Maybe it's a story that stands out among others in terms of its sadness.
The phrase 'la triste historia in english the only story' is quite puzzling. 'La triste historia' is Spanish for 'the sad story'. The 'in english the only story' part seems out of place or perhaps it was an attempt to say that there is a sad story which is the only story when translated into English. It could be that there is a collection of stories in Spanish and this one sad story is the only one being considered for an English version or something along those lines. Without more information, it's difficult to be more precise.
A 'historia visual novel' could be about various things. It might be a story set in a historical context, with characters and plots that unfold in a way typical of visual novels.

Since visual novels are a diverse genre, those with a historical focus might not always get the same level of mainstream attention. But in the communities dedicated to visual novels and historical fiction, there may be some well - known 'historia visual novel' titles that are highly regarded for their storytelling, art, and historical accuracy.
One main difference is the romantic plot in the fictional Anastasia. In the real - life story, there was no such obvious romantic angle related to Anastasia's survival mystery. Also, the fictional Anastasia might be depicted with more heroic or overly dramatic traits compared to what we can assume about the real Anastasia. The real - life Anastasia was a young girl in a very difficult and tragic situation, while the fictional one is often more of a fairytale - like character for the sake of the story.
