Hmm, some things to note in this video:
- J-Hope is stuck in a room and peering into the vent
- J-Hope's military enlistment date on a poster on the wall
- The clock on the wall set to his birthday (2:18)
- A pill and glass of water set on the side table (reference to BTS' Wings era)
- The toy airplane on the floor (reference to J-Hope's Hope World album)
- Zooming out of the vent and realizing the room J-Hope is trapped in is in a box that another J-Hope is holding
- The Snickers bar, the "Arson" lighter, and the "More" key in the drawer (references to BTS' Love Yourself era and J-Hope's Jack in the Box album)
That's a lot of Easter eggs in a 43-second trailer, but all we gotta know is that J-Hope is ready to escape his past and start his new era with a bang.
