just an observation and a theory i thought of; what if this comeback is related to the reflection of their past selves? judging from the teaser last night, there are scenes that are similar to old mvs before such as pretty u; the settings also gave off mature vibes which means +

that seventeen is in their adulthood stage already; they've followed their paths and enjoyed their youth in heng:garae so in this cb they're all grown ups, and it might be bc they have a lot of responsibilities and work to do, so now they're looking at their past selves to remind

them that they should balance their life by working hard, playing hard and resting hard. this is kinda making sense as seventeen has been imitating members a lot lately; and they also showed a mirrored formation in their choreo from last night which is most likely a spoiler ++

and is related to the idea of this thread. this is just my late night thoughts though, i can't assure my theory to be correct— and idk if someone has posted a similar theory so it might be a coincidence if there is one of the same idea as mine.
