That the author quit Episode just before releasing the finale. 
I hope she’s doing well, anyway. Yes, I’m talking about Adrenaline lol.
Another one of my favourites is The Dragon Bride by EarlGrey, and my least favourite part was the ending. 
In her defence, she was kinda backed into a corner plot-wise. But the ending really messed me up. 
Still 10/10 though.
