Ok so you can start requesting here, you can do it on any chapter but it's just easier if they're all together. That being said I don't really care either way.

Here's a list of fandoms you can definitely do, but it's not limited to this. These are just more likely for me to know of. (also if you choose Homestuck give the type of romance, like human romance, ♥️,♦️,♠️, or ♣️.)

Homestuck
Soul Eater
Fairy Tail
Undertale
Inuyasha
Guidestuck (technically a Homestuck AU but meh)
