The amber light of afternoon slanted through the high windows of the lecture hall, casting long shadows across the rows of attentive students. Haruto sat near the front, notebook open, his pen hovering above the page. Professor Yanagihara, known among students for his demanding intellect and ruthless questioning, stood at the front with a look of measured amusement.
"Many of you come to university expecting to be filled like vessels," the professor began, pacing slowly. "But knowledge is not poured—it is earned. Now—" he stopped and turned sharply toward the students, his eyes scanning—"who among you can explain the Fermi Paradox in context with current galactic habitability models?"
Silence. Not a shuffle, not a whisper. Haruto's heart pounded.
Professor Yanagihara's gaze landed on him.
"You," he said. "Mr. Takahashi, isn't it?"
Haruto swallowed. "Yes, sir."
"You gave a decent presentation last week. Let's see if your knowledge runs deeper. Enlighten us."
Haruto stood slowly. His mind raced, but he remembered the quiet nights on his dorm rooftop, the stargazing sessions with Aiko, and the countless hours spent buried in astronomy books.
"The Fermi Paradox," he began, voice steady but cautious, "is the contradiction between the high probability of extraterrestrial life and the lack of contact or evidence. Given the billions of stars and potentially habitable planets, we should've seen signs of intelligent life by now."
The professor raised an eyebrow. "And how do recent galactic habitability models factor into it?"
Haruto nodded. "Recent models suggest that galactic habitability isn't uniform. It changes with time and location—due to supernovae, gamma-ray bursts, and chemical evolution. So intelligent life may emerge in specific windows of time. We might be early… or late."
A murmur rippled through the room. Professor Yanagihara smiled, though not warmly.
"Well-argued," he said. "But tell me—what do you believe?"
Haruto hesitated. "I believe… intelligent life is rare. Not because it's impossible, but because surviving long enough to communicate across the stars might be the real challenge."
Yanagihara nodded slowly. "A thoughtful answer. Most quote facts. Few risk beliefs."
As Haruto sat back down, breath releasing in a slow exhale, he saw Aiko through the open door—waiting just outside, sketchbook in hand. She had finished her classes early and had come to walk him home. Their eyes met briefly, and she smiled, her thumb pointing upward in silent applause.
The lecture ended, and students began to rise and stretch, buzzing about the unexpected turn. Haruto packed up his things, his mind still half in the stars.
"Mr. Takahashi," the professor called before he could leave.
Haruto turned. "Yes, Professor?"
"I'm organizing a special seminar next month. An interdisciplinary dialogue between the sciences and the arts. I want you to represent our department."
Haruto blinked. "Me?"
"Yes. Your curiosity and articulation surpass most of your peers. Think of it as… a challenge."
Haruto nodded slowly. "I'd be honored."
"Good. I expect your topic proposal next week. Don't disappoint me."
Outside the building, Aiko looped her arm around his. "You looked like a philosopher up there," she teased.
He chuckled, still riding the high of the unexpected recognition. "Felt more like a deer in headlights."
"You did great," she said. "What was all that about at the end?"
He told her as they walked. The idea of blending astronomy and art sparked something in both of them. Aiko's eyes lit up. "What if your presentation included visual interpretations? Like star-inspired sketches?"
"You'd draw them?" he asked.
She nodded. "Only if I get credited as a cosmic consultant."
They laughed, the sound of it rising between passing cars and commuters. The city moved around them, but for that moment, they moved in a bubble of shared ambition.
Over the next week, Haruto dove into research, crafting a presentation that merged the silence of space with the human longing to understand it. Aiko sketched galaxies bleeding into cities, starlight reflecting in quiet eyes, and the lonely beauty of the cosmos mirrored in human lives.
When Haruto submitted the proposal to Professor Yanagihara, it wasn't just an answer to a challenge—it was a declaration. Of his voice. Of their journey.
And in the quiet afterward, with Aiko's hand in his, he realized that even among the daunting questions of the universe, it was their small moments of courage—together—that lit the path forward.
