Later that evening, Lena returned to her room after training. Her shoulders were sore, and the weight of the day clung to her like mist.
She slipped off her glasses, set them on her desk, and was halfway through tying her hair up when—
"So."
She froze.
Satoru Gojo was standing upside-down on the ceiling like a cursed bat, sunglasses slightly askew, arms crossed.
"Are we just laying on boys now? Is that what we're doing?"
Lena didn't even blink.
"You were spying. Again."
She grabbed her glasses, slid them back on, and met his gaze with the kind of tired resolve only siblings shared.
"Not spying," he replied smugly. "Observing. Protectively. With infinite concern."
