The knife thing actually does sound familiar. I think in a certain culture there was a thing where the husband gave the wife a knife and if he ever betrayed her she was allowed to kill him with it
Only one that comes to mind is the Altarans from the Wheel of Time. They had that entire thing of the wife recieving a kinfe to apply to their husband if he ever diespleased them (or otherwise). No idea whether that has any roots in a real historical culture though.
I love how it has a few pages of epilogue that's full part of the main story. Really makes it more complete when we get to see a few snippets of their lives as a couple instead of just ending with an "and then they totally got together afterwards!"
I'm going to imagine they go to school the next day and she tells them not to bully her girlfriend.
Granted, maybe not the very next day, and it won't be a strong rebuttal, but this is what ought to happen next.
Other than that...
I feel like the ending was good enough. Could've been better obviously, but I figure there's a good chance that a continuation longer than 5 pages would've made for a worse overall story. Knowing when to stop writing because you don't have anything left to tell with it is a good skill to have really, and sometimes it might be better to stop early rather than late.
I like the ending well enough, but I think it could be well-served with an omake-epilogue.
I think it's right that the general male population don't expect to like romance-focused works, especially ones which don't have a stereotypical masuline male lead [main character] with masculine personality traits, traditionally male interests and so on.
Which is why I'll be surprised if I ever see a (romance focused) work with a weak, introverted, insecure, or otherwise non-masculine male lead.
I blame society for making femine traits taboo for males and for making too many great things feminine traits (like skirts -.-)
So there's definatively a bias from society that dictates what you feel you "should" be into and not, which influences what you're willing to try and how you're willing to try it.
That said, personally part of what attracts me is the main characters' perspective as a female. Because i've always been curious as to how being a girl would be like (lately i've been wondering if I might be somewhat genderfluid even). And also because because the main character will always be somewhat removed from the stereotypical male traits that men are supposed to conform to (I refuse to do so btw). So for those reason's I have a certain preference for female protagonists in general, as they pretty much instantly break the conventions I struggle with society having (even when I don't encounter them directly very often) while also satisfying my "curiosity" (for lack of a better term <.<).
Homosexuality in works in general is something which just interests me. At least in part because I can sympathize a bit as a member of a different minority group (asperger's syndrome), plus I like stuff which challenges society's conventions. Besides that, f it goes deeper than "different and exiting" I don't know yet tho <.<
Yuri in particular satisfies my desire for fluffiness, which you don't really find in sterotypical male interests.
