Future Story Topics? | Frerard

So, if anybody hasn't read my Blind AU Ferard Fanfic here, you really should.

What I'm wondering if there are any other topics that are rarely used or that you wished you could see in fanfics. I'm looking for something that would be a challenge to write just like blindness was for me. But without making it over-the-top and hard to work with. I tend to be someone who, because of my depression and anxiety in real life, are able to connect better with writing sad or drama-filled stories along with some fluff and humor to even it out.

Anyway, basically, this is also just a shoutout to anyone who hasn't read my story. It's great. :)
