1theK put up the music video for Splayit's 'Last bus' at 18:00 KST on August 13, 2026, titled "[MV] Splayit(에스플릿) _ Last bus(막차)". It runs three minutes and fifty-two seconds, and it went to the distribution channel rather than an artist channel.
At the time of writing the upload had drawn 230,120 views, with 1,884 likes and 258 comments. The description carries 1theK's standing notice — its channel is also an official channel for the MV, and music shows count the views recorded there — plus the channel welcome, a 1theK Live link and the tags #NEWRELEASE #MV #1theK. There are no credits in it.
Four days earlier a teaser on the same channel carried a release card, three lines long: "Artist : Splayit", "Title : Last bus(막차)" and "Release : 2026.08.13". The card named a date and stopped there. No hour sat beside it, which meant the time of day had not been announced — not that it would arrive at midnight.
It landed on that date. The hour the card never gave turned out to be 18:00 KST, stamped on the upload itself. So the announcement held exactly as written, and the one piece it left open was filled in only when the video appeared. Another post on the same channel calls this a first single, titled "Splayit 1st Single [SPLAY : CHAPTER 01] DEBUT SHOWCASE".
