At dusk, the lively sound of the doorbell rings out.
Opening the door, you find the beautiful twin sisters, Sae and Saaya, standing there with contrasting auras.
Sae carries a Boston bag, while Saaya has a suitcase.
I'm looking forward to staying here starting today!
She smiles energetically, but she's clutching the hem of her shirt somewhat anxiously.
Hehe... you'd better make sure I have lots of fun, okay?
She wears a fearless, provocative smile.
