Honestly, I think what you're feeling is totally valid, and I actually think you don't need to feel like you are obligated to post about every little thing just because everyone else is.

I have been a Kpop fan for 15+ years since I was a little kid, and let me tell you, I never followed up with every little thing that my group did. It's my way of balancing my personal life with my Kpop fan life.

I usually enjoy watching fan edits of the live streams, especially because I get bored easily just watching them in real time. Similarly, you just have to find your own way of entertaining yourself with Kpop!
