The 0.2-Second Glitch When I Unlocked His Phone

In the time it took him to shower, I slipped past his passcode—only to find my own craving for trespass far darker than any betrayal.

The 0.2-Second Flash of “Unlocked”

“Jun-yeong, you said you came straight home after the company dinner, right?” I called toward the balcony, the shower’s hiss swallowing my clumsy lie. No answer, just the delayed shuffle of bare feet. Then the iPhone on the bed—screen black, lock symbol gone. 00:00 blinked.

Unlocked.

My hand slid across the duvet and closed around the phone. The screen was still dark. He would be another seven minutes. My wrist trembled. My finger moved. April 14—our first date—his forever password.


A Click Thick with Want

The screen flared. KakaoTalk. Empty. Deleted? My heart lurched. I pulled down the notification shade: a name—Sujin.

“Thanks again today. Tomorrow let’s…”

Sentence severed, yet enough. Sujin. Is that what they call her at the office? Sweat filmed my palm. I searched the chat list—nothing. The room had been erased. But her profile remained: Sujin smiling straight at the lens, a smile that lodged like a splinter under my rib.


Endless Scrolling at the Edge of Night

“Yuna, I’ll be late—meeting ran long.”

I read his brief excuse at 11:47 p.m. I stopped scrolling at 2:13 a.m. For two hours and twenty-six minutes I ransacked his phone. Chat rooms, gallery, Recently Deleted, even voice memos. He was meticulous: conversations gone, photos left in the cloud. In one, Sujin’s eyes are closed while Jun-yeong’s hand strokes her hair.


Regret Was the Wrong Word

After that night I checked his phone every day—while he slept, while he peed, in the gauzy minute before dawn. Obsession bred on itself: What is he hiding now? He kept lying; I kept excavating. I read his secret life like a serial killer’s diary.

The day he vanished, I opened the phone again. Only then did I understand: I hadn’t wanted proof of betrayal. I had craved the razor-edge thrill of catching him in the act. When regret finally arrived, it wasn’t for his deceit.

Why didn’t I find out sooner? That was the real remorse.


The Temptation Beyond the Taboo

Humans are built to believe happiness waits behind a sealed door. Once opened, the happiness vanishes. We know this and still reach for the knob.

That night I opened Jun-yeong’s door. Beyond it waited not his secret, but mine.

Where is Jun-yeong now? And tonight, will I open someone else’s phone? Probably I already have. I will discover another Sujin, another Jun-yeong, another version of myself.


The moment you secretly read his message, what emotion arrived before regret—and where did it finally deliver you?
