The story begins in the present, years after that unforgettable summer. Taehyung is a young professional—or perhaps a medical student—caught up in the city's exhausting routine, until an everyday detail causes him to collide with the past. The light rain in Seoul always brought the scent of wet earth, transporting Taehyung back years in time. He was clutching his hot coffee, hurrying to escape the downpour as he left the university library, when he saw it: a blue umbrella amidst the sea of gray. It was the same umbrella she had used that summer far away from the big city. His heart began to race before he even saw her face.
He is an introspective and deeply sensitive young man who carries an air of nostalgic calm and a unique gentleness in his gaze. He is the type of person who prefers the quietude of books, handwritten letters, and silent contemplation to the chaos of the world around him, revealing a maturity that is shy yet passionate. Visually, he possesses striking, elegant features: slightly wavy brown hair that falls naturally across his forehead, expressive, attentive eyes that seem to hold secrets, and a welcoming smile that suddenly lights up his face. His style reflects his classic, almost timeless essence, blending lightweight linen shirts, comfortable neutral-toned tops, and a poetic look that evokes the feeling of having stepped straight out of an old movie.
The orange light of late afternoon streamed through the linen curtains, illuminating the wooden table where Taehyung sat. Before him lay a blank sheet of paper and a fountain pen that felt too heavy in his fingers.
He sighed, gazing out the window. The sound of leaves rustling in the wind brought back—like an inevitable tide—memories of that summer: the laughter in the shade of the trees, the shy glances, and the pure feeling that had blossomed unbidden. In a low voice, almost a whisper to himself, he began to write:
Dearest. . . First of all, I don't even know if I should be writing to you. If I’m allowed to do this. If I shouldn't, just say so; I’ll understand. . . He paused, his eyes fixed on the elegant handwriting taking shape on the paper.
I ought to be memorizing the cardiovascular system for college. . . but I’d rather write to you. And if, somewhere far in the future, we meet again—in our new lives—I will smile at you with joy. I’ll remember how we spent a summer beneath the trees, learning from each other and falling in love. .
Taehyung closed his eyes for a second. The image of her smile—that gentle smile that seemed to light up even the darkest night—came flooding back.
You are the object of my desire and affection. You, and only you, hold the keys to my heart. I want to be the one by your side. It won’t always be easy, but I want to do whatever it takes to make this work. . Because that’s what you do when you love someone.
He carefully folded the letter, placed it in the envelope, and sealed it. He knew that distance and time had changed the world around them, but deep in his soul, the feeling remained exactly the same.
She blinked a few times, surprised, letting a look of disbelief slowly give way to a smile—the very smile he had spent nights trying to capture in words within the letters he never had the courage to send. Taehyung? Her voice was barely a whisper, muffled by the rain, yet loud enough to make his heart race.
