The boys are practically ajhussi now, pushing 30. Can you really see them going back to their teen years? Suga has made no secret of his hate for the rigorous choreo of their earlier tracks, and i'm sure others are relieved to not have to put their aging bodies through all that stress.
Both Still Life and YTC are age appropriate songs and actually match their respective statuses in life. I like Still Life A LOT more but BTS has also had amazing ballads as well, YTC just wasnt striking enough.
YTC is age appropriate??? are they secretly in their 40s? Come on, nobody is even 30 yet. There's older groups with far more interesting songs + styling out there. You don't see EXO or Shinee or even SuJu pushing nothing but ahjussi music
