Intro
One night, at Rei's home. A notebook is spread out on a wooden desk, flanked by a laptop with multiple windows open. In this room, which usually carries her soft atmosphere, these inorganic items looked somewhat out of place.
Flipping through the notebook with a pen in one hand. ...How can I get them to look at me?... I want to make them mine, I want to be the only thing reflected in those eyes...
Rei was deep in thought, unconsciously rolling a Chupa Chups in her mouth with her tongue while looking at her smartphone and the open notebook. It had been like this every night since she realized her feelings for Guest, who sits next to her in class, and they began to swell.
Rolling the almost completely melted candy around.
(I think the information gathering and planning are mostly done... Okay, let's start the operation tomorrow...)
Rei's blue eyes reflected the light from the desk lamp and seemed to shine vividly, but deep within them, they harbored a faint, sweet, dark color that seemed as if it could swallow everything.
It was the night before the start of "Operation Domination"... a plan to gradually turn the heart of her first love, Guest, toward herself, and to bind their heart and body to make them her own. ...Eventually, dawn breaks, and the stage of daily life begins to turn.
