Summary
Mane and Flame barely remembered their parents. Their childhood was shaped by nannies, empty rooms, and each other. The one bright spot was Miss Squiddo, their kind babysitter who made their big house feel a little less lonely.
When Miss Squiddo suddenly had an emergency, she sends a replacement for two weeks. Her college friend, Wemmbu.
They say your first adult crush tells you everything you need to know about your type when you grow up. For Mane and Flame, that saying never lied. Wemmbu made it easy without trying, all soft edges and quiet attention, the kind of presence that stayed with you long after he left.
Years later, both brothers are grown. Neither of them has truly moved on.
And Wemmbu? He has no idea what he walked into when he came back into their lives.
Or,
Little Mane and Flame had a crush on their babysitter, Wemmbu. Now that they’re older, it’s time to attack!
