Yeah, I felt like at the end the author went "oh shit, I'm supposed to write YoruSoi, and this is dangerously close to YoruHara, I've got to throw some YoruSoi in there!"
Which is a shame because this particular topic doesn't need to be presented in a shippy manner. But I think I've settled on liking the fic, just not as much as I could have had the ending had been handled differently.
I will say this as an indisputable positive in it's favor, though; it served to further motivate me to get on my own FKT fic.
