Intro
Your phone buzzed persistently against the desk before lighting up with Jisu’s caller ID. "Please, just show up for thirty minutes!" her frantic voice pleaded over the deafening chatter of a crowded pub. "The seniors are pouring drinks like crazy, and I'm practically holding up this entire table alone. You still owe me for covering your attendance last week, so don't you dare hang up!" Backed into a corner, you reluctantly threw on a jacket and headed toward the familiar basement tavern near the back gate. The moment you pushed open the door, the thick haze of grilled food, cheap soju, and raucous laughter washed over you. It was the typical, chaotic sight of a department welcoming party running at full throttle. Just as you paused near the entryway to search the crowded room for Jisu, familiar banter cut through the noise from the center booth. "Kang Yoonhyuk, what do you mean 'sweet, free booze'? You’ve got full-day lectures tomorrow, senior! Do you even plan on graduating this year?" "I'm gonna do it this year," came a familiar, lazy drawl. Yoonhyuk was leaning back against the vinyl booth with a carefree smirk, clinking his shot glass without an ounce of shame. "Jinsu’s been giving me morning calls every day, right?" "Being in the army was easier," his roommate Jinsu groaned, rubbing his temples in utter defeat. "I can't believe I have to live with this guy for another year..." You instinctively took a half-step back, planning to slip away unnoticed. But before you could turn, your gaze followed the direction Yoonhyuk’s attention had been drifting toward just seconds prior. Sitting across the aisle was a freshman girl, slumping heavily over a half-empty glass, her cheeks flushed bright red. The soft features and delicate face instantly struck an unwelcome chord in your memory—she was the spitting image of Jeong Dajeong. Jeong Dahye, Dajeong's younger sister. "Hey, Yoonhyuk," Jinsu murmured suspiciously, catching the direction of his friend's gaze. "Are you interested in her? You keep glancing over at her like a total creep. Don't tell me you've fallen for some love-at-first-sight nonsense..." Before Yoonhyuk could brush off the accusation, his sharp, dark eyes shifted toward the entrance—locking straight onto yours. The lazy indifference in his expression instantly gave way to a flicker of genuine amusement. Completely ignoring Jinsu's questioning, Yoonhyuk lifted his hand and casually patted the empty seat right beside him. With several drunken upperclassmen already turning their heads in your direction, retreating into the hallway was no longer an option. You forced a composed face and walked over, taking the seat while keeping a rigid, deliberate distance between the two of you. Yoonhyuk rested his chin on his knuckles, his amused gaze tracing your defensive posture before his voice dropped low over the surrounding roar of the pub.
