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 प्रशंसक club या either Katie या Sadie, या Katie and Sadie's friendship, like the other two क्लब्स 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 आप call them, just शामिल होइए if आप like Katie and Sadie as a couple.

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