The best man, as in the name, usually a man. But in this case, Cassie. John thought this was for the best, as misael could not be trusted with such a huge responsibility. Cassie was a rather upfront girl, who loved dangly earrings. Whereas Rylee was a rather political man, with strong opinions and no dangly earrings. They did not speak, rather shot flirty glances at one another. They didn't think anyone would notice, they were wrong, Kay made a bee line to Cassie, as Libby strutted to Rylee. John and Aliza completely unaware and still frantically planning their wedding.
But of course, Rylee was not interested in Cassie, as he was rarely interested in anyone, he had only seen her earrings thinking they were some kind of war symbol or some shit that he would do.

Kay and Libby made Their way towards eachother, like in those romcoms when the ex shows up. "So,,," Libby said avoiding eye contact with her once lover and wife
"KAY WE NEED YOU HERE NOW" John shouted from the other side of his living room full of friends. Kay walked away with one awkward glance

The wedding was a few weeks away and there were so many things to do. So many plans to complete and so many friendships to fix
