If Ara had to describe Seo Minjae in one word, it would be quiet.
Not the same kind of quiet as hers.
Her quiet was avoidance—staying small, staying unnoticed.
His quiet was observation—sharp eyes behind glasses, always watching, always thinking, as if the world were a puzzle he was slowly taking apart.
He sat near the back of the classroom, by the aisle, close enough to hear everything and far enough that most people forgot he was there.
Most people.
"Ara, can you take these to the faculty room?"
Their homeroom teacher dropped a stack of graded quizzes on her desk.
"Yes," she said automatically.
"I'll come too," Kang Joon added, standing up before the teacher could ask for another volunteer.
The teacher blinked, then smiled. "Good. Go together."
Ara shot him a look. "You don't have to."
"I want to stretch my legs," he replied. "And I don't like letting you carry heavy things alone."
"It's paper."
"Very heavy paper."
She sighed but didn't argue. Saying no only made him more stubborn.
They left the classroom together, the door sliding shut behind them.
As soon as it did, a low murmur rose.
"Are they close?"
"Do you think they're dating?"
"Han Ara? No way, she's like a ghost."
At the back, Seo Minjae flipped his notebook closed.
He hadn't looked at them once while they were talking, but his pen had stopped moving the moment the teacher said Ara's name.
Now, he lifted his head, gaze settling on the empty seats by the window.
He adjusted his glasses.
Interesting.
In the hallway, Ara shifted the stack of papers in her arms. "You don't have to keep following me everywhere," she muttered.
"I don't," Kang Joon agreed. "But I want to."
"That's worse."
He huffed a small laugh. "You make it sound like I'm some kind of stalker."
"You show up on the rooftop, in the hallway, at lunch—"
"That's called 'being classmates'," he said. "And besides, you're easy to find."
"How?"
"You always go where it's quiet," he replied. "Rooftop, back stairwell, library corner. If it's empty, you're probably there."
His accuracy made her uncomfortable.
"You notice a lot," she said.
"So do you."
Her fingers tightened on the papers. "You don't know that."
He didn't argue. He just smiled slightly, like he'd already decided something about her and was waiting for her to catch up.
When they reached the faculty room, Ara knocked and stepped inside to hand over the quizzes. Teachers thanked her, barely glancing up.
On the way back, they took the side stairwell. It was quieter there, the echo of their footsteps bouncing off the walls.
Halfway down, Ara stopped.
Someone was sitting on the landing, back against the wall, long legs extended, one knee propped up.
Seo Minjae.
His tie was loosened, his bangs falling into his eyes as he scrolled through something on his phone. He didn't look surprised to see them.
He looked like he had been expecting them.
"Skipping class?" Kang Joon asked lightly.
"Teacher sent me to check on the AV room," Minjae replied, not moving. "I decided the AV room is fine."
"That's not how errands work," Ara said before she could stop herself.
He looked up at her. His gaze was clear, cool, the kind that made people straighten without realizing it.
"You don't talk in class," he said. "But your voice works fine out here."
She frowned.
"Seo Minjae," he introduced himself, as if they hadn't shared the same grade for years. "We were in the same middle school, Han Ara."
She blinked. "We were?"
He didn't seem offended she didn't remember.
"Third year. Different class," he said. "But I remember you."
"Why?"
"You cried at the back of the library once," he replied, tone matter-of-fact. "I was returning books. You thought no one was there."
Her cheeks flushed hot. "You're mistaken. That wasn't me."
"It was," he said. "You were hugging your knees and mumbling numbers under your breath."
Her heart lurched.
Numbers.
Jaemin's countdown.
Had she… said them out loud?
Kang Joon glanced at her, expression shifting. "I didn't know that," he said softly.
"Because it's not true," Ara snapped, more sharply than she intended. "You're remembering wrong."
Minjae tilted his head, studying her.
"You always say that," he murmured. "Even when you know you're right."
She opened her mouth, then closed it again.
Kang Joon stepped between them slightly, not enough to block her, but enough to draw Minjae's attention.
"Why were you watching her in the library?" he asked.
"I wasn't watching," Minjae replied. "I was there first. She didn't notice."
"Then why remember it now?"
"Because it wasn't the only time," Minjae said.
Silence thickened.
"I've seen you check the air above people's heads," he said to Ara, as if commenting on the weather. "Your parents at parent-teacher day. Your friend at the school festival. Sometimes you look relieved. Sometimes you look like you're going to throw up."
Her blood ran cold.
Her grip on the stair rail turned white-knuckled.
"I don't know what you're talking about," she whispered.
Minjae's eyes were too sharp, slicing through her lies.
"I thought it was just a weird habit," he continued. "But then Jaemin died."
The name hit her like a slap.
Her breath hitched.
Kang Joon's jaw tightened.
"And on the day he died," Minjae went on, "I saw you on the road, screaming his name, looking not at his face, but," he tapped a finger in the air above his head, "up here."
Ara's vision blurred.
The world narrowed to the sound of her own heartbeat.
If he said one more word, she might break.
"That's enough," Kang Joon said quietly, voice low but firm.
Minjae shifted his gaze to him. "You're the transfer student."
"Kang Joon."
"You weren't here then," Minjae said. "You didn't see her after the funeral. How she started avoiding everyone she cared about. How she stopped looking people in the eyes."
"I said that's enough," Kang Joon repeated.
There was no anger in his tone, but something about it made the air feel heavier.
Minjae studied him, then shrugged.
"I'm only stating what I've seen," he said. "I like patterns. Han Ara is a pattern that doesn't make sense yet."
"I'm not a pattern," Ara forced out, her voice low. "I'm a person. Stop talking like I'm some… math problem."
He considered that. "People are just complicated equations."
"I don't care how you see other people," she said. "Don't look at me."
"That's difficult," he replied frankly. "You stand out."
"I don't."
"You do," both he and Kang Joon said at the same time.
They glanced at each other.
For a moment, something unspoken passed between them—a measuring, a quiet acknowledgement that the other was not easy to fool.
Great, Ara thought weakly.
Just what she needed.
One boy with no time, and one boy who noticed too much.
"I'm leaving," she muttered, brushing past them. "Enjoy… whatever this is."
"Ara."
She didn't stop.
If she stopped, she might hear more.
Might answer questions she had spent years burying.
Back in the classroom, she sank into her seat by the window, fingers trembling as she opened her notebook.
Her eyes burned.
He remembers the library.
He saw me on the road.
How many times had she thought she was invisible, only to realize someone had been watching from the edges?
Her gaze drifted to the door just as it slid open.
Kang Joon stepped in first. Minjae followed a few steps behind, expression unreadable.
Their eyes met across the room.
Minjae didn't smile. He didn't look away either.
He just lifted his hand and tapped the space above a random student's head, as if to say: I know you look here.
Ara's stomach twisted.
She snapped her eyes back to her desk.
Minutes later, when class started, she stared at the board but absorbed nothing.
Her rule had protected her from loving people.
It had not protected her from being seen.
At the end of the day, rain drizzled against the windows again.
Ara went to the rooftop out of habit, craving the cold air.
She stood alone for a few minutes, hugging her cardigan around herself, the city a blur beyond the fence.
"Running away?"
She didn't have to turn to know who it was.
"I'm taking a break," she said.
Kang Joon came to stand beside her, leaving just enough space between them that she could pretend it didn't matter.
"From class?" he asked.
"From… questions."
He was quiet for a moment.
"Minjae talks too much when he gets interested in something," he said.
"I'm not 'something'."
"That's what I told him."
Her lips twitched. Just a little.
"Were you… angry?" she asked.
"A little."
"At him?"
"At the idea that you'd have to remember that day because of him," he said.
She stared at the wet rooftop floor.
"You're not going to ask me if what he said is true?" she whispered.
"I'll wait until you want to tell me," he replied.
She exhaled slowly. The knot in her chest loosened, just a bit.
"You shouldn't get involved," she said. "With me. With Minjae. With any of this."
"Too late," he said.
She glanced at him. "Why?"
He tilted his head back, looking at the low clouds.
"Because," he said, "ever since I came back here, things keep almost happening."
"Almost?"
"The vending machine. A car that should have hit me last week, but didn't. A glass that fell in the cafeteria and somehow didn't shatter when it hit my foot," he listed calmly.
Her heart pounded. "And you think… that has something to do with me?"
"I don't know yet," he said. "But I know this: you're the only one who looks at me like I should have a countdown and don't."
Her breath caught.
She hadn't even realized she'd been doing it.
"I never—"
"Ara."
He turned his head to meet her eyes.
"Whatever you're afraid of," he said softly, "I'm not going to disappear just because you look at me."
You don't know that, she thought.
You don't know what happens when I love someone.
But she didn't say it.
The words lodged in her throat, heavy and trembling.
Instead, she stood there in the thin rain, listening to the quiet rhythm of his breathing beside her, the distant noise of traffic below,
Her fingers tightened slightly against her sleeve.
No.
She shouldn't let herself think like that.
Because every time she did—
something broke.
