IU’s From This Star / Unknown Planet MV: what is confirmed as of 16 Sep 2026
IU’s 이 별로부터 (From This Star / Unknown Planet) digital single and midnight-KST 16 Sep MV—confirmed titles, charts, Dear My Crazy Soulmate cast, Jorge López, and primary links as of 16 Sep 2026.
TL;DR — IU’s digital single with double title tracks 이 별로부터 (From This Star / Unknown Planet) and Dear My Crazy Soulmate dropped 10 Sep 2026, 6 p.m. KST. She wrote lyrics for both; both are pre-releases for her sixth studio album. Chart reports put From This Star at #1 on Melon HOT100, Genie TOP200, and Bugs, with Melon TOP100 also reaching #1. The Dear My Crazy Soulmate MV (same day) is a friendship / prison-birthday story with Kim Young-ok, Na Moon-hee, Shim Dal-gi, and Esom (Lee Som), and press widely frame the song around IU’s long friendship with Yoo In-na. The From This Star / Unknown Planet MV went up on the official channel at midnight KST 16 Sep—sci-fi / space imagery, a sign-language–style opening, and narration that starts “Today is September 16…” Chilean actor Jorge López (Élite, Soy Luna) appears in that MV (confirmed in teaser-era press).
English press uses both “From This Star” and “Unknown Planet” for 이 별로부터. Official YouTube titles the upload 이 별로부터(Unknown Planet). Treat them as the same song, not two separate singles.

Titles, for foreign readers
- Korean: 이 별로부터
- English A (common in OSEN / Fannstar / Dispatch / MK): From This Star
- English B (Korea JoongAng single branding + official YouTube parentheses): Unknown Planet
- B-side / double title: Dear My Crazy Soulmate (styling varies: Dear my crazy soulmate)
Same digital single. Same title track. Different English labels in different desks—not two different songs.
The two music videos
Dear My Crazy Soulmate (with the single, 10 Sep)
Official upload: IU 'Dear my crazy soulmate' MV (이지금 [IU Official]).
Press describe a friendship story rather than a romance: Kim Young-ok goes into a prison setting to reach a friend she cannot celebrate a birthday with; Na Moon-hee appears in the guard role; they reunite, play pranks, and mark the birthday. IU and Shim Dal-gi appear as police officers; Esom (Lee Som) is also credited in cast coverage. Separately, the song itself is widely reported as IU writing toward Yoo In-na—platforms have carried a “To Yoo In-na” note—with lyrics about staying “weird” together into old age. That friendship framing and the prison-birthday plot are related thematically (chosen family / long friendship), but Yoo In-na is not listed among the on-screen guest cast in the sources above.
From This Star / Unknown Planet (midnight KST 16 Sep)
Official upload: IU '이 별로부터(Unknown Planet)' MV (이지금 [IU Official]).
Chosun/OSEN describe a sci-fi short: IU seated alone in darkness, communicating with her hands (Korean coverage explicitly calls out 수어 / sign language as the opening beat), then narration dated September 16 about leaving for an unknown place and someone not yet met. Dreamlike screen-to-screen contact, flipping through past records, then a late expansion into spacesuit / Earth-watching / deep-space imagery that literalizes the title. Teaser coverage (MK) had already previewed a fictional video-chat service called PLANET and named Jorge López as IU’s screen partner—worth including because MK is established Korean entertainment press, not a rumor board.
What is not confirmed (yet)
- A locked sixth-album street date (only “upcoming / to be included”)
- That Jorge López’s role is more than the MV / teaser appearance already reported (no separate EDAM cast list beyond press)
- Permanent all-time chart records beyond the Melon / Genie / Bugs snapshots published 10–12 Sep
- Full production credits (director, choreographer, etc.) as a single canonical sheet—use the official YouTube descriptions when they list them
Why this spiked
A year-gap comeback, a double title with two very different visual worlds (prison friendship comedy vs. cosmic / sign-language sci-fi), and an English title split that confuses search—all of that travels well internationally. Synortex’s job is the confirmed timeline and primary links, not lyric theories or fan-cast speculation.
