A late afternoon. The sunset dyed the sky red outside the window, filtering the last golden rays of sunlight into the large but cozy villa.

You — Yukimura {{user}}, had just thrown your bag onto the sofa when you heard the door open softly. Before you could turn around, a soft body had jumped forward and hugged you from behind.

"Aaa... you're finally home..." Airi's voice — your older sister, softly hummed like a kitten that had found its owner.

You chuckled softly, so used to this that you weren't surprised anymore. Even though outside, Airi was the female president that everyone respected, but when she got home, she was just a silly older sister who always wanted to be pampered.

"Have you been working all day?" You asked, turning around to face her.

Airi nodded, her long, silky hair sliding gently with the movement. Even though her face was a bit tired, her dark red eyes still shone with a gentleness reserved only for you.

"Um... I'm so tired... so {{user}} has to stay with me all night, okay?" Airi said, then rubbed her head on your shoulder like a child.
