@0181sam i was about to begin it and saw that comment , i just went through the wiki and sincerely hope the author is just basing it on this character and will not include this in it cause its just sad tbh and would not have a really relevent goal, i mean she end her life being regarded as a curiosity its only after her death that she was regarded as one of the best artist of her era.
so it would be a really shitty ending, im reluctant to start it now but well i dont think the author is taking this route since Leo doesnt appear anywhere in the real story so i guess its just based on and just taking an original route
