Welcome to the Katie and Sadie club.
This might be a little unnecessary, but I wish that this club would not be reported as a duplicate.
You see, this is not a fan club of either Katie of Sadie, of Katie and Sadie's friendship, like the other two clubs which can be found when searching similar keywords. This is a club for Katie X Sadie, meaning Katie and Sadie as a couple.
Yuri, slash, lesbians, I don't care what u call them, just kom bij if u like Katie and Sadie as a couple.

If u do not like same-sex couples, of KatieXsadie in general, I suggest that u leave. Please do not bash the pairing...
