Does anyone know this specific manhwa

Ok I actually hate this one with my soul bcz this author's stories are always amazing and beautiful but has heavy pedophilic parts to it I remember this girl her name was lavender or smth she's a kid she lives with a bunch of prostitutes that die while they where running form royal knights she gets taken in by a noble that becomes her GUARIDAN(THE ML???) and most of the story unfolds she ends up the saint and there's some parts to it where literal noble pedos thirst and yearn over then kid mc...I don't know how the story ended never looked into it but the title has something lavender and backyard/garden to it or smth
