Why are forbidden relationships so common now

Alright, why is it that like 50% of protagonists are not attracted to any cat in their own clan?? How hard is it to not fall in love with someone from another clan in yet another forbidden romance?? The options are not that limited istg the options are not that limited TwT (especially for Thunderclan Cats)

I may or may not be absolutely done with forbidden relationships (i just want someone to find someone in their own clan so they don’t have to do the challenges for like 6 chapters)

(I’m rereading A Starless Clan atm because I can’t trash on the new arc without being up to date and I’m just so confused about all this.)

edit: just for clarification, id Rather this than more incest, I just wish there was an alternative to both of these rather than continuing them
