Hearts2Hearts put the 'Next Chapter' MV teaser on their official channel at 6:00 PM KST on October 13. It runs 24 seconds, and at the time of writing it carries 202,389 views, 22,323 likes and 1,579 comments.
The description opens with the title line Hearts2Hearts 'Next Chapter', and the date and time 2026.10.16 6PM (KST) sit on the line below it. That date falls three days after the post went up.
Beneath the date the description says Arena of Valor's 10th Anniversary is coming, and then says to celebrate with Hearts2Hearts. That is the full wording on the anniversary. The post says only that Hearts2Hearts is celebrating it.
Further down come a copyright line, the group's official channels and hashtags, including NextChapter. The post does not say what the date refers to beyond the MV teaser.
