The post-holiday atmosphere at Seoul National University was thick with a heavy, sluggish energy. The transition from the warmth of home-cooked meals and family banter back to the cold, clinical precision of the Computer Science labs felt like a system reboot that was taking too long to load.
For me, the day started with a variable I couldn't control: a mandatory meeting with the Student Council and the Dean's office regarding the freshman scholarship program. As the top-ranked student in the department, my presence wasn't requested; it was required. It was the kind of administrative red tape I loathed—hours of sitting in a stifling board room, listening to seniors argue about budget allocations while my mind was miles away, anchored to a specific desk in the third-floor library.
By the time I escaped the meeting, it was already past noon. I gripped the heavy, insulated lunch bag Eomma had insisted I take. Inside, the containers were still warm—prime short ribs, seasoned spinach, and her signature lotus root.
"Give it to that classmate," she had whispered with a wink as I left the house. "A girl who works that hard needs to eat well."
I navigated the crowded hallways with a sense of urgency. I hadn't seen Danoh all morning, and the "Shadow" in me was restless. I felt like a program running in the background, constantly scanning for a specific thread of data.
I reached the student lounge near the lab, a place where freshmen often gathered between lectures to study or gossip. I spotted her almost immediately, sitting at a corner table littered with textbooks and printouts.
I started toward her, my hand tightening on the handle of the lunch bag, but I stopped dead in my tracks.
She wasn't alone.
Shin Sunho was there.
He was leaning over her table, but it wasn't the distant, professional posture of a Teaching Assistant anymore. He had pulled up a chair close to hers—too close. He was holding a small, steaming cup of premium coffee, which he placed gently in front of her.
"You've been here for three hours, Danoh-ya," Sunho said. His voice, usually meant for the whole class, was now dropped to a soft, intimate register. "Even the most dedicated student needs a break. Drink this. It's a special blend from the café near the main gate."
I watched from behind a pillar, my pulse beginning to thud in my ears like a warning siren.
Danoh looked up, her expression shy. "Oh, Sunho-sunbae... you didn't have to. Thank you."
"I wanted to," he replied. He reached out—not to touch her, but to gently push a stray lock of hair away from her eyes so she could see her textbook better. It was a gesture of effortless, practiced care. "I noticed you were limping a bit less today. Is the leg healing well?"
"Yes, much better," she murmured, taking a small sip of the coffee.
Sunho smiled, a warm, radiant expression that seemed to light up the dim lounge. "Good. If you need anything—anything at all—don't hesitate to message me. I've already told the other seniors to look out for you. You shouldn't have to carry so much weight on your own."
I felt a cold, sharp bitterness coat the back of my throat. It wasn't just jealousy; it was the realization of a tactical error. While I was playing the silent protector from the shadows, Sunho was stepping into the light. He was doing exactly what I wanted to do, but he was doing it with the polish and social grace of a "perfect senior." He was offering her the warmth that I, in my silence, often struggled to express.
He was caring for her. And he was doing it in a way that felt natural, whereas I felt like every move I made was a calculated risk against my own nature.
I looked down at the lunch bag in my hand. Eomma's galbi suddenly felt heavy, like an anchor. I couldn't walk over there now. Not with Sunho sitting there, occupying the space I wanted to inhabit. I didn't want to be the third person in that frame. I didn't want to see her look at him with the same shy gratitude she gave me.
I waited. I stood there, hidden by the architecture of the building, watching as Sunho stayed for another ten minutes, chatting easily, making her laugh—a soft, tinkling sound that usually belonged only to the quiet corners of my memory.
Finally, Sunho's phone buzzed. He stood up, patting the table twice in a friendly gesture. "I have a seminar. See you in the lab, Danoh."
I watched him walk away, his posture confident, the quintessential "hero" of a campus drama.
I moved then. Not toward her, but toward the empty chair next to her bag while her head was buried back in her notes. I moved with the silence I had perfected over twenty years of being a shadow.
I reached the table. She didn't look up; she was deep in a complex algorithm. I quietly set the insulated bag on the edge of her desk, right next to the coffee Sunho had bought her. I didn't say a word. I didn't tap her shoulder.
I retreated immediately.
I walked to the upper mezzanine, a balcony that overlooked the lounge. From there, I could see everything without being seen. I leaned against the railing, my breath shallow.
A minute passed. Then two.
Danoh reached for her pen and paused. She blinked, her eyes landing on the unfamiliar bag. She looked around, her head turning left and right, searching the crowded lounge. She looked confused, perhaps even a little startled.
She slowly pulled the bag toward her. She opened the zipper, and I saw her shoulders drop as the scent of the food reached her. She pulled out the small note Eomma had tucked inside—a bright yellow post-it with a messy heart drawn by Harin.
She knew.
Even from the mezzanine, I saw the shift in her expression. The shy, polite smile she had given Sunho was replaced by something else—something deeper, more vulnerable. Her hand lingered on the warm container. She looked up again, her eyes scanning the room with a renewed intensity, searching for the shadow she knew was nearby.
She took out a piece of the galbi, eating it slowly. A small, genuine smile broke across her face—not a smile of social politeness, but a smile of comfort.
I watched her for a long time. I watched her finish the meal, her movements relaxed, the tension from Sunho's presence seemingly replaced by the familiar warmth of my home.
Only when I was certain she had eaten enough, and that her focus had returned to her books with a newfound energy, did I turn away.
My knuckles still throbbed slightly, and the "Ice Prince" in me was still reeling from the sight of Sunho's hand near her hair. But as I walked toward my next lecture, I realized that the variable of Shin Sunho didn't change the equation.
He could offer her the light. He could offer her the coffee and the polished words.
But I was the one who knew the exact weight of her bag. I was the one who knew the sound of her breath when she was scared. And I was the one whose family's warmth was now sitting inside her, keeping her grounded.
The shadow doesn't compete with the light. The shadow simply waits for the light to fade so it can prove it's the only thing that never leaves.
I straightened my posture, my expression returning to its cold, unreadable mask.
"Let him try," I whispered to the empty hallway.
The game had changed, but the protector remained the same.
