I never thought I would discover betrayal in such a cruel way.

That night, I lay beside Jang Daehyun, listening to the steady rise and fall of his breathing. The room was quiet, but my mind wasn't. A strange unease coiled in my chest, an unsettling weight that refused to let me rest.

My eyes drifted to Daehyun's phone, resting just inches away. I hesitated. I had never been the type to check someone else's phone—I trusted Daehyun. But tonight, something felt different.

With a shaky breath, I reached for it. The screen lit up, and my world stopped.

Daehyun's profile picture.

My heart pounded violently in my chest. It wasn't our picture. It wasn't me.

A woman stood beside Daehyun, smiling, close—too close. They looked happy, comfortable, like something deep existed between them. A chill ran down my spine as realization set in, heavier than anything I had ever felt before.

With trembling hands, I tapped on Daehyun's profile, desperately searching for an explanation. But when I tried to view it from my own account—

"This account's posts are private."

A sharp, bitter laugh almost escaped my lips. I had been hidden. Shut out.

Beside me, Daehyun shifted slightly in his sleep, completely unaware of the storm raging inside me.

My fingers curled tightly around the phone. My breath came in short, uneven gasps.
