I think it depends on the amount of "stanning" and of course no kpop should not be above life responsabilities.
I for once only watch my faves videos one or two times when they come out and that's it. I don't go crazy spending hours watching the same videos over and over. The music it's different because I do listen to a lot of it.
So if you feel you're doing enough that doesn't affect your life then it's good
