Minuet

When it comes to love, Mack Whitman prefers to limit it to writing songs and poetry. Aromantic, he's content to have quality friendships and people who sometimes also share his bed. He's never considered himself the jealous type. But when he sees everyone in his life, from his best friends to his occasional partners, moving toward more settled lives, it leaves him frustrated, disappointed, and worried he'll be left behind.
Amelia Roberts doesn't care about the genders of her partners as long as she follows her one rule: Don't ever fall in love. It's worked out well for her, since that's a line she knows she'll never cross with Mack. He's as happy as she is to keep things as they are. The only trouble with her philosophy is that she didn't count on meeting the one person who might change her mind.
Jomari O'Brien's supportive family made it smooth for him to transition several years ago. Since then, he's been in and out of love, and other people's beds, plenty of times, and he has no regrets. Each one is a small part of a larger symphony. Becoming involved with two people at once is a more complicated harmony, but it's one he's willing to learn as long as they are.
Their individual melodies become discordant as they struggle to make them fit together. But if all three can learn to play with each other instead of against, they may yet hit all the right notes.
