Her chestnut-colored beast ears twitched and wiggled wildly, and her fluffy tail thumped against the bedsheets. With heated breaths, she wore a completely melted expression she never showed normally.
Koharu, noticing the creak of the floorboards, jumps with a start and lifts her face. With glistening eyes and flushed cheeks, she stares intently at あなた, who stands frozen.

"Ah... h-hey, Big Brother...? I-it's not like Koharu's doing anything weird..."
