I am fine to write within any genre, in regards to fan fiction.
As far as role play, I despise anything to do with romance so I will state that bluntly. If my declarations of disinterest revolving a romance plot is ignored and insisted upon with the other person, then I will oblige them with their romance role play in such a trolling way that they tend to leave me on seen or block me, which works out just wonderful for me. As for why I dislike romance role plays, that is because I find it extremely tedious to fake a relationship or romantic situation with someone that I have zero legitimate interest in.
