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 팬 club 또는 either Katie 또는 Sadie, 또는 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 당신 call them, just 가입하기 if 당신 like Katie and Sadie as a couple.

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