what people think girls playing house is like: "teehee, I'm gonna pretend to marry the boy I like!"
what it's actually like: "my husband was murdered by my ex-lover, I must go to the mountains to train for my revenge."
Emma is a woman of culture. Kind of weird that a 35 year old married woman, would offer to let an 11 year old child feel up her tits. Bizarre. But an enjoyable yuri experience for the characters and the audience.
