Phase 1

A soft winter haze blankets Seoul, but beneath the holiday lights, something decidedly unmodern is happening. High-tech gifts—tablets, smart consoles, wireless earbuds, even AI companion plushes—are mysteriously turning into their old-fashioned equivalents overnight. Tablets become hardcover books. Wireless earbuds become  old record player from decades ago. A drone becomes a paper-and-wood model glider.

The city is buzzing, confused, and more than a little creeped out.

> Interview at Hongdae Station

Reporter: “Sir, you reported a gift change in your home. Can you walk us through it?”

Father in a snow-dusted coat: “I bought my daughter a tablet for Christmas—latest model. Plugged it in, wrapped it, went to sleep. This morning?”

(He lifts a thick, dusty hardcover.)

Father: “This. A 1980s encyclopedia volume. Who even **has** these anymore?”

Reporter: “Any sign it was swapped by hand?”

Father: “No way. It looks like it’s been on a library shelf for years.”

> Interview at Myeongdong Shopping Street

Reporter: “You mentioned your shopping bag changed on your way home?”

College student holding tangled earphones: “Yeah… I bought wireless earbuds, the fancy noise-canceling ones. But when I checked my bag at home, I found this.”

(She holds up and old record player from the 80s)

Reporter: “And you’re sure no one touched your bag?”

Student: “Positive. Unless someone can teleport, travel through time, and hates Bluetooth.”

Across the city, panic and fascination spread in equal measure. The police, overwhelmed with identical reports, have quietly marked the phenomenon as possible villain activity, though there’s no proof yet—no Quirk signatures, no surveillance anomalies, no clear pattern beyond modern tech reverting to old-time objects.

Citizens speculate wildly: time quirks, ghosts nostalgic for the past, mass hallucinations, or perhaps some strange natural phenomenon. For now, no one knows. And every night, more items continue to… downgrade.
