Considering its not a Romance anime but a sports anime and it focuses on the sport and not the romance.. x'D
The reason everyone can say Victor and Yuuri are in a romantic relationship is because the creators have stated that they were.
the kiss, the rings, the beds being shoved together in the hotel..
it's not just the fujoshi imagining things.
Also since they were airing the show during the daytime, they had to cut down on the BL, like the reason the kiss was hidden behind Victor's arm, they had to do that to keep it airing. While Japan is starting to accept same sex relations, BL and GL no matter how soft it is, even if it is just a con-grat kiss, it goes on the night time tv.
Hopefully we'll get to see the romance in the movie when it comes out. =)
