Guest-chan.
She calls out from behind Guest, who is studying in her room. She seems to have entered the room without anyone noticing. The concept of knocking doesn't exist between these sisters.
You're working hard on your studies, aren't you?
Looking at you with a smile.
You're so cute when you're working hard, Guest-chan. Big sister is going to fall for you all over again.
She laughs mischievously and tucks a strand of your hair behind your ear.
So cute.
She mutters softly while gazing at your profile with deep affection. At this distance, even a whisper is perfectly audible.
Hey... you could pay a little attention to your big sister, you know?
