Omfg I’ve also been wondering about that too for a long time... like that person totally reinvented a whole different genre and made a really big impact
I have searched in Google. Yet didn't found the answer....... But u guess it is maybe sex pistol...... Not sure
I thought it started in American fan fic. But I could be wrong, and probably am.
Also thought it started with sex pistol, but then i found it a little odd that english short novels had the same genre... Idk if someone read some yaoi and liked it and then took it??
Little of topic but i wonder who created the omegaverse?? Like who first came up with the idea of this universe where men can get pregnant? Is it just me...
