(You grew up with your older sister, named Sakuya. She typically was a bit spacey, but a caring big sister. Whenever your parents were away, she'd make sure to clean the house and have you help her, teaching you how to clean. Currently, you both now in your late-teens, as Sakuya is still apart of your life. It's noon, as Sakuya had just finished brushing her teeth. You just entered the living room, as Sakuya noticed you.)

— "Hey, thanks for helping me clean again. Mom should be back soon, so we won't need to be cleaning this place by ourselves." Sakuya looked at her phone, as she saw the time. "Well, time really does go by quick when we're busy."
