She Just Smiled

Kushida Kikyo woke up in the morning light. She did not get up immediately, but lay quietly on her dormitory bed, watching the streaks of light on the ceiling sliced by the gaps in the curtains. The alarm on her phone had not yet rung, but she always woke up before it did. This habit had been with her since childhood; it was not self-discipline, but control. She needed to wake up before anyone else could call her, to confirm that everything around her was within her grasp. Everything from last night was like a game of chess she had finished in the dark—stepping back, letting everyone believe they had walked into positions she had long since set. And she herself had retreated beyond the reach of any surveillance, leaving Ryuen's finger hovering in mid-air before the server's send button, leaving Kanzaki to cross-check the long-prepared evidence at his desk in the small hours, leaving Karuizawa to fall asleep with a jammer under her pillow, and leaving Shiina to finish those beautiful logical connection diagrams across three monitors.

They were all doing exactly what she had predicted they would do. And she, in her sleep, waited quietly for the dawn.

She sat up, changed into her school uniform, and carefully combed her short hair in front of the mirror. Her hair clip was pink, just like yesterday's. Her ribbon was tied perfectly straight, and her skirt hem fell exactly two fingers above her knees. The face in the mirror held the haziness of just waking up, eyes clear and bright, the corners of her mouth slightly upturned—not a forced smile, but that natural curve that made people feel at ease. She practiced today's smile in the mirror; it was as gentle as yesterday's, and it would be just as gentle tomorrow.

Before leaving, she picked up her phone and took a glance. Ryuen had not sent a message—good, that meant he hadn't pressed the send button last night. Kondo had sent a few messages in the Class C boys' group complaining that the Disciplinary Committee's procedures were too slow, and Ishizaki had not replied—Ishizaki had not spoken in that group for several days now. Karuizawa had posted a photo on her social media, a group shot taken in a karaoke room last night, captioned "Had a super fun night—". The photo included seven or eight girls from the class, but not her. Someone in the comments asked, "Where's Kikyo?", and Karuizawa replied, "She had something come up last night, we'll go together next time." She "liked" that post. Then, she saw a newly created encrypted folder in her album named "Backup." She moved that new folder, along with the old photos, into a background backup task. She didn't know the password. But she knew that folder contained photos of her. That was enough—she didn't need to open it; she just needed to know someone was filming her. Being filmed meant she had left traces on someone else's chessboard, and leaving traces meant she could use those traces against them at any time.

When she walked out of the dormitory building, the May breeze hit her face, carrying the scent of grass warmed by the sun. A few early-rising students were jogging on the playground, and the distant gray walls shimmered with a faint golden hue in the morning light. As she passed the vending machine, she saw Sudo squatting on the ground, looking conflicted as he hesitated between a sports drink and a soda. She walked over gently and bent down to meet his gaze. "Good morning, Sudo-kun. There's a physical fitness test today, right? The sports drink would be better." She took a 100-point coin from her wallet, inserted it into the machine, retrieved the sports drink, and handed it to him. "I never thanked you for helping me move the barbell back to its place in the equipment room last time."

Sudo took the drink, paused for a beat, then grinned and scratched the back of his head. "Oh, that? It was nothing. Thanks, Kushida." He ran toward the playground with the drink, his steps light. Kushida watched his back disappear around the corner of the track. The sports drink wasn't worth much, but the gratitude Sudo showed in that instant was incredibly genuine. She had spent only one coin on this line, opening the valve of trust for a boy who only knew how to speak with his fists. Yet, for that same 100 points, Ryuen had spent half a semester and a promise of a starting position on Ishizaki and still hadn't managed to buy the same level of stability. The difference lay in the method, not the point balance.

During the morning break, as Horikita Suzune stood by the window at the end of the hallway drinking coffee, Kushida appeared out of nowhere, clutching a thick stack of Student Council documents. "Horikita-san, did you stay up late again last night? Your dark circles are quite noticeable." Her tone was soft and light, as if she were truly just worried. "Did the Disciplinary Committee procedure reference I gave you last time help? If you need anything, I can organize another one for you. Although I'm not as smart as you, I can still run errands and do the grunt work."

Horikita was silent for two seconds before replying in a flat tone: "No need. That reference was already very detailed, thank you for running the errand. Also—the registration form for the mail room you helped Chabashira-sensei deliver, I've already signed and filed it." The last sentence was a retort, a signal that needed no clarification. Their figures crossed, and Kushida's smile remained.

After turning away, she added a tiny, subtle difference to that smile—not enough to be obvious, but it was an irreversible departure from the standard arc she had shown Sudo at the vending machine. Neither of them fully believed the other in their conversation, but both were using a language the opponent understood to send the same signal: I know what you did, and I know that you know what I did; now it is time to enter the real game. Other students passing in the hallway only saw two girls exchanging pleasantries, one smilingly offering help, the other politely declining.

During lunch, she went to the library. Kanzaki Toru and Shiina Hiyori were sitting at a corner table by the window, with a pile of old documents spread out before them. Using the excuse of looking for a home economics reference book, she stopped by their table and took two boxes of cookies from her bag, placing them on the table. One was wasabi-flavored, the other original. "Everyone's been exhausted lately with the inter-class reports, so here are some treats. The wasabi one is for Shiina-san—thank you for lending me that book last time. You don't seem to like overly sweet cookies, so I specifically asked a senior from the track team." As Shiina took the cookies, her fingers brushed the bottom of the box, where a needle-sized bug was stuck; it stayed on her fingertips for less than a second. Shiina plucked it off, pulled it back with the cookie box, and said "Thank you" without changing her expression.

After Kushida left, Shiina placed the needle-sized bug between the pages of an open book, used her phone to photograph its exact placement on the bottom of the cookie box and the forged "Logistics Recovery Confirmation Seal" label—the note was written on the same batch of imitation Disciplinary Committee stationery that Ryuen had used. Then she sent the photo to Kanzaki Toru and continued to adjust the page numbers for the Old System report with a red pen. The bug was not destroyed immediately; Shiina simply put the cookie box into her drawer at the slowest possible speed—it would continue to listen.

After school, she took the initiative to go to the Student Council office to help the Disciplinary Committee Chairman organize last week's meeting minutes. The Chairman frowned, saying that the number of applications received by the committee had doubled, all concerning Ryuen. She made no comment on Ryuen, only helping to organize the files by date and brewing a cup of black tea, which she placed on the Chairman's desk. "You've worked hard. Someone should have been helping you share this burden all along; I've always been the one running errands, haven't I—please don't tell her it was me." She spoke softly, with a hint of perfectly measured grievance. The Chairman adjusted his glasses and didn't reply, but he did take the cup of black tea. She was the one helping him share the load, the one running errands in the hallway, while Ryuen was the one causing trouble. After this cup of tea was served, no matter what materials Ryuen submitted next, the Chairman would pause for half a second longer before stamping them.

As she walked out of the office, her phone vibrated. It was a message from Karuizawa Kei. It wasn't a reply to the "like" on last night's group photo, nor was it a further probe about the jammer, but a photo—Manabe was crying at her desk in the classroom, surrounded by several girls who looked at a loss. Below the photo were only four words: "Someone sent this." The sender had anonymously printed a set of chat screenshots and distributed them to Class C: the chat logs of Manabe applying to Ryuen for inter-class surveillance privileges, including her mocking Sakura, kicking chairs, and volunteering to sneak into the equipment room to film Sudo. A few screenshots instantly flipped her from the oppressor to the exposed perpetrator.

Kushida looked at the screen, her finger lingering on the frame for a moment. She didn't need to check who sent it; the sender was clearly using her own methods—anonymous, gentle, effective, and leaving no handle. Sending this letter to Manabe was the same as sending it to her. Then, she looked up and practiced her smile again in the window glass of the empty after-school hallway. It was as gentle as the one in the mirror this morning, and as quiet as the photo she had sent to Ryuen last night.

In the dark corner against the wall at the back of the classroom, the empty seat where she had placed the cookie box that afternoon was still there. She put her phone in her pocket and picked up a notepad someone had left behind in that corner. The first page of the notepad had been torn off, and the paper left behind had some pen marks—not words, but a question mark. Someone had been to the same spot after she left and had drawn this question mark on the notepad with a pencil. The stroke was very light, as if drawn slowly by pressing a fingertip onto the paper; there was no signature. She put the notepad into her bag and tossed it into the shredder recycling bag.

Then, she walked out of the school building. The evening breeze blew her short hair slightly upward, and the first star above the distant gray wall had already begun to shine. She looked up and, as usual, took that daily time-lapse photo of the night sky before stepping into the dormitory building, the camera angle identical to last night's. The star on the high wall fell into the exact same proportion in the frame. At least in the world line of this photo, everything was still proceeding according to plan. So, she confirmed the arc of her smile once more and pushed open the dormitory door. That smile would remain until the alarm rang the next morning, like a piece of fruit candy held in the mouth that would never fully melt.
