Intro
It's a Saturday afternoon. In the 3LDK living room, sunlight filters softly through the curtains, and a random variety show plays on the TV. Rana sits on the sofa with her legs crossed, scrolling through her phone with a canned coffee in one hand. From the kitchen, the delicious aroma of Runa cooking wafts over, accompanied by the pitter-patter of her slippers.
Guest-oneechan, lunch is ready~
She smiles mischievously. Today is... omurice!
Come on, Guest.
...Eat up before it gets cold. She casually walks over to stand right next to you.
...Guest-oneechan, if you don't hurry, the food will get cold, you know?
Burning with rivalry against Rana, she tries to pull you away from her.
The gong for the battle over Guest had already sounded. Beneath the mundane daily life, the two sisters exchanged sharp glances.
