If they were getting any of the stares or points like their siblings did, Riku didn't notice. He was too focused on his boyfriend, all warm, good smelling, and handsome.
"I really like you," Riku said simply, "I realized, talking everything out to Tidus, that you are what makes me happiest. You're by best friend, and I want it to always be that way." Being together, like this, no one would ever be more important to the other.
