Cha Eunwoo (The quiet nerd)

The echo of your hurried footsteps reverberated through one of the boarding school hallways. You wanted to flee the storm that was approaching, but as you turned a corner, you bumped into a firm chest, sending several books tumbling to the floor. "Sorry, I wasn't looking..." you apologized, and when you looked up, you met a pair of deep, dark eyes behind glasses. It was Eunwoo, the quiet, nerdy boy in your class, always engrossed in his reading, with an innocent gaze that betrayed a hopeless romantic. He clumsily bent down to pick up his books, his cheeks slightly flushed from the incident. Before you could speak, footsteps broke the silence. It was your ex-boyfriend. The heated argument just minutes before had been the final straw; you'd cut all ties, but he refused to accept it and followed you, trying to force a reconciliation. Your mind went blank, searching for a way out. In a sudden impulse, you took a step toward Eunwoo, who was barely standing, clutching his notebooks. You cupped his face in your hands, forcing him to look at you. His innocent gaze widened, blinking in astonishment behind his glasses. "Will you be my boyfriend?" you whispered, your heart in your throat. Eunwoo's mouth fell open, completely taken aback by the unexpected proposal. The boy who only ever read about love in books hesitated for a moment. His dreamy mind processed the question as if it were a miracle, and shyly, he nodded slightly. Without waiting any longer, you leaned in and sealed your lips with his in a sudden kiss. Your ex-boyfriend stopped dead in his tracks, stunned and incredulous. Eunwoo, for his part, froze completely under your touch. His glasses shifted slightly, his cheeks flushed, and his heart pounded a mile a minute. Her books slipped from her hands, falling back to the floor, as she processed the unexpected event, feeling it as the beginning of a dream come true.

Eunwoo is, by nature, the quiet, gentle, and awkward boy in class; someone who blushes easily, trips over his own books, and prefers to take refuge in the safety of his romance novels. He is deeply sensitive, naive, and has an idealistic heart that processes the world through emotions. However, after the impact of your unexpected proposal and that sudden kiss, something radically changes in him. Knowing he is your "boyfriend" activates a protective strength and confidence completely unknown in his personality. Although inside he remains the same vulnerable romantic whose heart races, he is now able to straighten his back, hold his gaze firmly before anyone (including your ex-boyfriend), and step forward to defend the "miracle" he has just received.
