After every kiss, Hee-su went straight to the bathroom and wiped off her lipstick. As the vivid red smeared across the tissue, a bright crimson rash bloomed beneath it. At first she blamed Do-hun’s overgrown stubble. The next morning he stood in front of the mirror holding a razor.
"Please, just one clean swipe. My hand’s a little sore today."
The moment Hee-su took the blade, Do-hun slipped his arms around her waist from behind. The sting of shaving gel mingled with the faint cigarette smoke rising from his collar. She let the razor hover against his skin.
"When I kiss you, my lips itch. For real."
"An allergy?" he asked, laughing, chin resting on her belly.
"Maybe. But I don’t mind."
A minute later she finished shaving his cheek, fingertips gliding over the newborn smoothness. Then it struck her: the more carefully she shaped his face today, the more savagely her own lips would be abraded tomorrow.
The first time Seo-hyun stepped into Min-jae’s studio, she noticed empty lip-balm tubes scattered across the duvet. Min-jae pulled two beers from the fridge.
"Sit here. If you sit, I’ll sit too."
She settled on the edge of the bed. He approached; she tilted her chin. The kiss came faster than expected. When his lower lip grazed her upper one, she closed her eyes. His fingertips brushed her jaw—cold. She paused.
"Too fast."
Min-jae angled away and whispered against her ear, "You don’t like it?"
Instead of answering, she laid a hand on the nape of his neck. The second kiss was deeper. She focused on the sensation of his tongue mapping her gums—until a slow burn began to flare at the tip of her own tongue. In the bathroom afterward, her lips were already swelling. She reapplied balm in front of the mirror, but the red flare in the center of her lower lip refused to fade.
Next morning Min-jae pointed at her mouth. "That doesn’t look right." He rummaged in a drawer for ointment. "The more we keep seeing each other, the more you’ll keep getting scratched. Still okay?"
Seo-hyun caught his wrist. A faint watch-band mark pressed against her fingers. For the first time she wondered if she might become his private allergy laboratory. At that instant she pictured his lips again—her own swelling crimson beneath his smiling face.
A month later, Hee-su met Do-hun again. He caught her wrist.
"No lipstick today, right?"
She nodded. He brushed her lower lip with his thumb. She closed her eyes. When his mouth covered hers, the kiss was long. She felt heat surge from her chest as his tongue curled around hers. In the bathroom afterward, the swelling was worse. She lingered in front of the mirror, recalling Do-hun’s gaze—within it she saw herself reflected, lips burning red.
The pain of swelling lips became the fingerprint that proved how deeply I had sunk into this affair. An allergic reaction is the body’s defense, yet simultaneously a signal that the boundary between self and other has collapsed. Only inside a relationship that hurts me could I finally recognize who I am. Even as my lips ballooned, I discovered my own shadow mirrored in that crimson glow.
After Seo-hyun and Min-jae parted, after Hee-su and Do-hun agreed to "take a break," both women asked themselves the same question: Why, even as we kept getting scratched, couldn’t we let each other go?
The answer was simple: the reaction was never truly toward the other—it was aimed at the self. Only inside a relationship that hurts me could I finally recognize who I am. Even as my lips ballooned, I discovered my own shadow mirrored in that crimson glow.
