Cherry Berry can overlook her lack of wings and even that the mare she fancies is a Princess of Equestria. What she can't get over, however, is that said mare is an immortal alicorn. Is the "alicorn problem" a big enough deal to deny them both the happiness they find in one another?
SHE CHERRY ON MY BERRY TIL I RUMINATE ON MY IMMORTALITY
Without reading the fic, I only consider this sort of thing problematic insofar as large age gaps are problematic. Like, there's always going to be one member of a friend group who outlives all of the others right? People have pointed out that this is an actual problem with "Twilight will not outlive her friends," because she'd likely outlive most of her friends even without her ascension and normal earth pony longevity covers the ones she wouldn't have.

Cherry Berry just has to perform a "princess-worthy task", and she'll become an alicorn herself. The hard part is figuring out what specifically qualifies as such...
