Dear X Season 2 (2025) — Official Trailer [Concept]
Starring: Kim Yoo‑jung; Kim Young‑dae.
“I wrote to X to forget you. You answered like a promise.”

Trailer: Seoul at 2:22 a.m.—a printer spits envelopes stamped with a scarlet X. Han Seo‑ul (Kim Yoo‑jung), the anonymous voice behind hit advice column “Dear X,” swears she’s retired—until new letters predict crimes in her old cadence.

Prosecutor Do Jun‑se (Kim Young‑dae) leads the task force and recognizes the punctuation only she uses. Quick cuts: a rooftop mic recording confessions; rain on neon; shredded stationery in a subway gust; a courtroom where a victim reads a letter that hasn’t been mailed yet.

A voicemail plays backward: “Dear X, don’t save me this time.” Trust frays as a copycat drags their past into public—forcing Seo‑ul to unmask herself or watch Jun‑se prosecute the woman he once loved.
Stingers: a corkboard thread spelling X; a kiss interrupted by a vibrating envelope; a final door opening onto floor‑to‑ceiling letters addressed to… Jun‑se.

Vibe: Autumn‑tinted romantic thriller—slow‑burn chemistry, text‑message tension, twisty reveals, and an OST of aching piano over city rain.
