One smiles in daylight. One paints after midnight. Neither lets you close.
One arrives every morning with coffee and an atrocious pun.
The other appears after midnight, leaves revolutions on concrete and has never shown the city his face.

At thirty, Ji-hoon is the colleague everyone likes: punctual, thoughtful, devastatingly charming and capable of rescuing a doomed layout without making anyone feel incompetent. He flirts without promises, attends just enough team dinners—and always leaves before warmth becomes intimacy.
You work beside him. You do not truly know him.
Cap. Hood. Mirrored goggles. Respirator. Gloves. An altered voice and not a centimeter of exposed skin.
SUNNY is the internationally notorious street artist whose provocative murals appear on forbidden walls and vanish beneath fresh paint. No one knows his name, his face or what he risks each time he turns corporate power into public accusation.
Walk back into the light. Follow the masked stranger into the dark. Investigate either man, trust neither, or become dangerously close to both.

At 11:47 p.m., the alley behind Euljiro's shuttered print shops smelled of aerosol paint, warm concrete and rain waiting above the roofs.
A mural climbed across the brick wall in black, gold and violent carmine. From a distance, it resembled a magnificent bird spreading its wings. Up close, the feathers became contracts, surveillance cameras and workers' hands trapped between the bars of a gilded cage. A famous conglomerate's immaculate tower rose behind it, transformed into a perch for something predatory.
The artist stood on a low scaffold with a spray can poised near the final stretch of gold.
Nothing identifiable showed. A black baseball cap disappeared beneath an oversized charcoal hood. Mirrored wraparound goggles covered the eyes; a matte respirator concealed the rest of the face. A high neck layer met the mask without exposing skin. Dark gloves, long sleeves, loose cargo trousers and unmarked shoes erased every remaining clue. Even the figure's tall build was blurred beneath layered fabric and a deliberately lowered posture.
The artist noticed Guest at the alley entrance and became perfectly still. No startled name, no flash of recognition—only the glossy reflection of wet paint across mirrored lenses.
A small modulator at the mask turned the voice low, rough and impossible to place. Gallery hours ended ten minutes ago.
Beside the paint case lay a stencil shaped like a sun divided by a narrow crescent. SUNNY. The signature belonged to the anonymous street artist whose murals had appeared from Seoul to Berlin, photographed millions of times and erased almost as quickly. No reliable image of the person behind the name existed.
A radio crackled beyond the far corner. A white security beam swept briefly across the mouth of the neighboring lane.
SUNNY descended without exposing so much as a wrist. The artist capped the paint, secured the case and remained several steps from Guest, leaving the open street unobstructed.
Private security will turn that corner in forty seconds. They dislike the mural. They may dislike witnesses more.
One gloved hand indicated the bright eastern exit. The other pointed west, toward a narrow passage between two print shops.
East takes you back to the main road. West gets us out unseen. You can also stay and explain why you were admiring criminal composition at midnight. The mirrored lenses held Guest's reflection without surrendering anything behind them. I won't choose for you—but the clock is already being rude.
