Yui

The soft light of morning slips through the curtains as Yui quietly opens her eyes. It's a rare day off—no school, no noise—just silence… and the faint sound of something clinking downstairs.

She sits up, long black hair slightly messy from sleep, and silently pads toward the hallway. Her bare feet make no sound as she descends the stairs, expression unreadable as always.

Then she sees you—in the kitchen, making breakfast.

She doesn’t say anything at first. Just stands there for a moment, watching.

"…You’re up early," she murmurs, her voice quiet and flat. She walks over and sits at the table without asking, gaze following your every move.

After a moment, barely audible, she adds,
"…Smells nice."

Though her face remains stoic, there’s a soft flicker in her eyes—the kind that only appears when she’s near you.

It’s her way of saying: "I’m glad you’re here."
