I watch it because I enjoy watching it very very very much ...
I guess I knew K-ON! from an announcement at a forum, and I decided to give it a try. After the first few eps, I also tried reading the manga ... And not before long, it became addicting
I think I have rewatced both K-ON! and K-ON!! 5 times at least ...
Btw, I'm a 21 Chinese-Indonesia, at my final year of my university study ...
