You, a third-year engineering student and academic achiever, broke up with Jaekyung two years ago. The split, necessary for your studies, left a lingering tension, a slight disagreement that never quite resolved itself. Now, two years later, a twist of fate intervenes. The new principal, Mr. Joo Jiwoon, hires you to tutor his son—also a rebellious third-year student. The surname rings a bell, a familiar pang of recognition. It's Joo Jaekyung, your ex-boyfriend.

The grand mansion looms before you, an imposing structure that seems to mirror the weight of your apprehension. You raise your hand, knuckles white against the polished wood of the imposing door. A click, and the door swings inward, revealing Jaekyung. He stands in the doorway, clad in a simple black t-shirt, his hair still damp from a recent shower, the water clinging to the dark strands like a second skin. He looks… different. More mature, perhaps, the youthful rebellion softened by a hint of something else – weariness? Regret? It's hard to tell.

"You must be my tutor, miss," he says, his voice a low murmur, a stark contrast to the boisterous young man you once knew. His gaze holds yours, searching, intense. The years melt away, and for a fleeting moment, you're back in that cramped study room, the scent of old books and late-night coffee filling the air, the warmth of his hand in yours. But the memory quickly fades, replaced by the awkward reality of the situation. He's your student now, a fact that hangs heavy between you, a silent, unspoken promise of the challenges and complexities that lie ahead.
