hm yes the angst from Murasakino is just *chef's kiss" but honestly I've been following this story since it came out and the only thing I can say is that we gotta wait for Eri's point of view about all of this. We can't pinpoint anything just yet because she hasn't admitted anything about how she truly feels since she's mostly oblivious about it as well. Let's also not forget about the first panel in which it showed Eri with her wedding dress beside her, calling Kyou and telling him to attend or something. tho I'm not sure if that's Eri (but yeah i think that's her because of the hair color) SHE'S PROBABLY MARRYING A RANDOM STRAIGHT DUDE THAT'S NEITHER KYOU NOR FUYUKI.
if she does realize how she feels and they end up communicating, maybe they're the ones getting married. if they do love each other and ended up not talking about it, then Eri is probably marrying another dude. the one I'm going for is my last take because I really think Eri has no romantic feelings towards Fuyuki and she's just all over their friendship, which also ends up with her getting married to another random dude in the future.
but it kinda makes sense if you think about it this way and if the story progresses furthermore showing Eri's point of view:
Eri did want Fuyuki to stay as her friend (AKA the promise of not betraying Eri and remain as her friend forever) and she thought it was just that until she started acting weird towards Fuyuki's relationship. That's weird I mean why the fuck would u act like that if you just see them as a friend so that's like Eri's problem that she hasn't figured out yet. IF SHE DOES FIGURE IT OUT, I believe she would then realize that she's the one who slipped and fell in love with Fuyuki (since all this time SHE'S CONVINCED THAT Fuyuki doesn't see her that way because of the promise) but maybe she would be scared at that point because she's the one who asked for Fuyuki to be friends with her forever. Also, it is possible that she loves Fuyuki and she just haven't realized it yet since she thinks that's just how special their friendship is for her.
