Obviously not. There are so many reasons someone might unstan a group and sometimes, it just happens for no particular reason.
I don’t know how old you are, but life can become tough. Sometimes, you simply don’t have the time, energy, or even the desire to keep stanning when your priorities shift.
Honestly, I’m the opposite. I can’t really imagine being that dedicated to a group or idol forever. I’d rather focus on my own life and just enjoy K-pop as a form of entertainment on the side.
