Man, I just watched the trailer, didn't know they released it like a week ago, because I was told this was going…
This is from the editing team for ticket to heaven on the trailer and why it was on the more lighter side: "In the first draft of the trailer, before the OST was finished, it was much heavier and gloomier than this. But when we sat down and watched it, it felt like we were repeating the same old path. Then, after hearing the song, we realized the thing still missing was ‘a smile.’ So we decided to focus on the inner struggle, and the question of whether, for the sake of that smile, walking this path is truly the right thing to do. The difficult thing about this #TicketToHeaven trailer was that the pilot itself was already so outstanding and powerful that it became one of the best works we’ve ever done. So instead of trying to replace it, we chose to tell the story in a different direction and mood, following the OST, which carries a brighter, more hopeful feeling. We wanted this to become a new beautiful memory that could exist alongside the original."
