Stories that pissed me off

I'm dropping it. And I'm upset bc this is so good. But like Aria should've gotten her happiness but then she dies from giving birth??? Why. And now it's about their kid going back in the past preventing idk them fucking? Or what?
I so don't like when authors don't know their limits when to end a story. Bc from then it's just gonna be a downfall. It's disappointing especially with good works. TT
