Dovewing x Briarlight
While Dovewing definitely reads as a closeted bisexual (though I imagine her with more of a lean towards masculine and male cats), I don't think that she is a great match for Briarlight. Sure, they do have great personalities, I feel that they compliment each other better as friends. They have high energy shenanigans and a child-like wonder that makes them fit well together as buddies. I feel that they'd be too immature to maintain a steady relationship.
