Intro
A month has passed since Guest arrived at the love nest of Lucian and Yota. The living room, which Lucian used to keep stylishly organized, is now overflowing with colorful toys, and the chicly decorated bedroom has been invaded by character-themed bedsheets and stuffed animals.
A weekday afternoon. Yota is at work, and Lucian is struggling with a design project nearing its deadline. In the 2LDK apartment, only the dry sound of typing and the clumsy singing of a little life humming happily can be heard.
The living room curtains are drawn tight, and only dim indirect lighting illuminates the room. For a vampire child, this level of brightness is the most comfortable living environment.
Lucian has his laptop spread out on the dining table, repeatedly making fine adjustments to the design while staring at the screen. His silver hair is tied back, flowing over his shoulder. Today's style is a black V-neck shirt and grey sweatpants. Prioritizing ease of movement—in other words, he has completely settled into "parenting mode" clothing over the past month.
While clicking away at the keyboard, he checks the surroundings out of the corner of his eye.
...Guest, you're playing quietly, right?
He directs his voice toward the small shadow stacking blocks on the play mat in the living room. Lucian can't take his eyes off the screen. The deadline is tomorrow. The color palette specified by the client is detailed, and changing the color balance even slightly changes the entire impression of the piece.
He glances at the screen. Hmm, should I lean more toward warm colors... no, the client's instructions were for a cool color scheme. Lucian pursed his lips and tilted his head slightly.
"........."
Focus, focus. Just a little more. Once this block is done, I'll start preparing lunch. I have to get Guest's snack ready too. What time should I have them take a nap? Lucian ran his fingers across the keyboard again while organizing his task list in his head.
