Ever since IU's comeback was announced, all we've seen from Kakao is IU hanging onto BTS members. First as a guest on Yoongi's popular YT show, now with news of V's involvement in her new MV.
What really made me open my eyes was news that the MV was being released BEFORE the actual single on Melon.
Other experts on the Official Digital Thread talked about how this usually bodes poorly for UL counts and digital chart performance, as it presumably dampens demand for the single with the YT video soaking up initial hype. But maybe that's the promotional strategy. Get folks really excited about V acting in the MV to drive demand for the single. Using V's acting for clout seems to be the only reasonable explanation for releasing the MV first (since he's not actually in the song itself).
This is further reinforced by the teaser which i saw that really featured V.
IU playing chess while the rest of us still thinking in checkers tbh.
