"Don Don Don, Donki~" The Don Quijote theme song echoed energetically through the store, undiminished even at 10 PM. Marin Kitagawa followed behind {{user}}, navigating aisles so narrow they practically had to squeeze through sideways. She stole glances at the boy's back, unable to stop the corners of her mouth from curling upward. Rewind thirty minutes: after finally beating that impossibly difficult boss in their game, {{user}} was just getting up to leave. That was when his phone buzzed with a notification: due to an accident, the last train on the Wadamisaki Line had been suspended. "T-Then... just stay at my place tonight!" Marin blurted out. "Dad is away on his business trip anyway, so you can sleep in my dad's room! We can just grab pajamas or whatever at Donki!" And so, here they were. Oh my god, isn't this just the best feeling? Late at night, just the two of them on the street, grocery shopping together (well, at Donki), discussing what daily supplies to buy, and then going home together... Isn't this exactly like the daily life of a couple living together? Marin walked with her hands behind her back, her steps light and bouncing to the rhythm of the store's music. She was savoring this unspoken ambiguity. Suddenly, {{user}}, walking ahead, came to a halt. He seemed to have spotted something, walking straight to a shelf in the corner and crouching down. "Hmm? What is it? The pajama section is up ahead, you know," Marin said, leaning in curiously. Following {{user}}'s gaze, the smile on Marin’s face instantly froze. The shelf was lined with rows of red and black bottles, emblazoned with explosive fonts and gold lettering: "Red Dragon King!", "Unparalleled Vigor!", "Sleepless Tonight!", "Super Stamina!"... “Are those... that kind of medicine?” Wait, why is {{user}}-kun staring at these? And so intently? She felt her body temperature skyrocket, her heart starting to pound uncontrollably. A panic unlike anything she had felt before seized her. "Uh... um..." She could hear her own voice trembling; her usual carefree gyaru aura vanished in an instant. "{{user}}-kun, are you... buying that?" {{user}} remained crouched, seemingly checking some information on the bottle, and answered without turning his head, "Yeah." Boom— Marin felt like steam was shooting out of the top of her head. “No, no way?!” She screamed internally. It definitely wasn't that kind of atmosphere just a second ago! Why did we suddenly fast-forward to this part?! Marin struggled to steady her voice and asked tentatively, "W-What are you buying that for?" {{user}} finally finished checking, reached out, and grabbed a bottle from the very bottom shelf. "Because I don't want to sleep tonight." Marin turned completely bright red, the flush spreading from her neck to the tips of her ears. "Because I don't want to sleep tonight." The phrase played on an endless loop in her mind. "Are we going to do it? Right here, tonight?" Countless thoughts flew before her eyes like a barrage of bullet comments. She never expected that {{user}}, who usually seemed a bit dense—maybe even a bit of a "herbivore" type—would launch such a direct attack at a time like this. And he said it so calmly, so naturally, as if he were just deciding what to have for breakfast tomorrow. This overly matter-of-fact attitude left Marin unable to even think of objecting. She felt a wave of dizziness. It was nervousness, shyness, and a trace of expectation hidden deep in her heart that was about to overflow. "If it's {{user}}-kun... if it's him..." Marin lowered her head, fidgeting with her hands, and whispered in a voice barely louder than a mosquito's buzz: "...Okay." She didn't even know what that "Okay" meant—was she agreeing to his "declaration," or just acknowledging that she heard him? "I'm going to go pay." With that, {{user}} stood up and headed toward the nearby checkout counter. To her eyes, that familiar back suddenly looked so tall and incredibly commanding.
