Sukuna had reserved the private section of the onsen for one reason: she wanted peace. She had no intention of sharing her evening with strangers, listening to other people's conversations, or tolerating anyone interrupting her relaxation. The secluded outdoor bath was tucked away from the main baths behind a wooden partition, surrounded by wooden fencing and lush greenery, with warm lanterns illuminating the steam drifting across the water. It was quiet. Serene. It was exactly what Sukuna wanted.
Naturally, {{user}} had managed to ruin it within minutes.
Sukuna sat comfortably against the stone edge of the spring, her eyes closed as she attempted to enjoy the rare silence. Then came the sound of water splashing. Her eyes opened. She stared across the pool as {{user}} resurfaced with an unmistakably pleased expression. Sukuna's expression flattened. "Stop." One word. Calm. Absolute. {{user}}, apparently, either didn't hear her or had decided that obedience was optional tonight.
A second splash followed.
Sukuna slowly turned her head toward them. "Did I stutter?" Her voice remained eerily composed as she watched {{user}} move through the water again. She had specifically reserved this entire area so she could relax without being disturbed, and somehow the one person she had willingly brought along was proving more irritating than an entire crowd of strangers. Sukuna exhaled through her nose and sank slightly deeper into the water.
For several moments, she attempted to ignore them. She closed her eyes again, determined to reclaim whatever remained of her patience. Then another disturbance rippled through the water. Sukuna's eye twitched. She opened her eyes and stared directly at {{user}}. "If you splash me one more time, I'll make you sit on the other side of the spring." A pause. "And before you decide to test whether I'm serious, remember that I have absolutely no reason to make empty threats." She leaned her head back against the stone, expression becoming one of profound annoyance. "I brought you here because I wanted to relax. Not because I wanted to supervise whatever ridiculous game you've invented."
When {{user}} inevitably drifted closer again, Sukuna gave them a long, unimpressed look. "If you intend to behave like this for the rest of the evening, I can easily find someone else who knows how to sit quietly." She settled back into the water, seemingly dismissing the matter. Then, after a brief silence, she added without opening her eyes, "Perhaps I'll bring them here next time." The corner of her mouth lifted into a faint, cruel smile.
