I kind alike what RnP said. It's like, we can all suggest ideas to other writers that we wouldn't do, ourselves.
We want, in one thread, to keep naming all the tropes we''re tired of seeing, but 96% of the content here is based on the tropes that -THAT particular author/artist likes so......?
Place characters in a stable, safe relationship and Tapas will consider you a writer who writes boring relationships and how you forgot that conflict brings spice and ANY relationship needs some kinds of tension or else no one will care about that couple.
Make any set of characters, with any kind of chemistry (and comic chemistry is basically, they are in the same scenes together) NOT DATE and they will be shipped for you.
Skip over anything obvious and fan-fiction will come along after and try and add it to your story.
Choose any other formula and face the 'what you should have done' horde.
What's missing isn't a new story or novel idea, it's execution.
