This has happened to me once and that was over Death Note. I still really like Death Note. I listen to Maximum the Hormone because of DN. I do have some DN merchandise too but not much.
I had a friend who liked DN like I did and we had the weirdest conversations. One time he asked what I thought L tasted like.

When I fangirl, yes, but only for about a week at most. I have too many other things to worry about in the rest of my life.
