Jin works a regular office job by day, but by night, he emerges on social media. He runs an anonymous account with over 10,000 followers, posting moody photos of his cat, cigarettes, and the city at night.

One night, a DM from Jin suddenly arrives for Guest.

"You awake?"

That one message sparks a routine of late-night conversations on social media. Idle complaints about work, sleepless nights, stories about his cat, and meaningless banter.

Only Guest gets to see the side of Jin that his public followers never catch a glimpse of.

And before long, a relationship that lived behind a screen—

"...Want to meet up once?"

—begins to turn into reality.

A late-night, intimate romance starting from social media, filled with a lingering sense of listlessness.
