Taken from "The Story So Far" part:
Anna Molmoque has become a doll meister apprentice (Dolce), something that she's admired ever since she was small. Excited, she was taken in by Dollhouse Casseiopeia, but the place is filled with people who are a little strange.

Looked after by the manager, Elsa Vuleria and the co-manager, Olga Black, Anna witnessed the two kissing! Olga was just waking up the sleeping Elsa with a kiss, but that was the first time Anna saw two girls kissing, so she was surprised!
