DK & Jeonghan's 'No-Clue' Trip Message

In the Korean comments

The comments offer two details to watch for. One top comment reads, in translation, “Why do they both look so young? I genuinely thought I’d put on an In the SOOP teaser,” while another jokes that their eyes look busy reading the script.

What the words mean

정답 없는 여행 (jeongdap eomneun yeohaeng, “a trip with no right answer”) is more than a poetic title. The captions explain that DK and Jeonghan continually choose Yes or No without knowing the “correct” path; the closing line then reverses the idea by declaring that every choice becomes the right answer.
