1theK put up a video titled "MIMI (OH MY GIRL) 'Bish Bash Bosh' MV Teaser (Bish ver.)" at 18:00 KST on August 14, 2026. It runs twenty-two seconds, and the version label sits in the title itself.
At the time of writing the upload had drawn 3,388 views, with 233 likes and 9 comments. Its description is a release card, three lines long: "Artist : MIMI(미미) (OH MY GIRL(오마이걸))", "Title : Bish Bash Bosh" and "Release : 2026.08.20".
That third line is a date and nothing more — no hour appears anywhere in the post. Two earlier cards in the same format show why that gap is worth holding open rather than filling in. A Splayit card reading "Release : 2026.08.13" arrived at 18:00 KST on its date. A Hearts2Hearts announcement that gave August 12 for both KST and JST, also with no hour, arrived at 00:00 KST.
Those two landed at opposite ends of a day — one in the evening, one as the day began. So for this card the honest position is that August 20 is fixed and the hour is not. Past the card, the description holds only a list of 1theK's own channel and social links, and nothing there adds to the date.
