Barbarian by Onley James

Nico Michaels pretends to be carefree, avoiding anything serious, especially relationships; his chaotic past has taught him that love only complicates things. He’s content with one-night stands and his close-knit group of friends, including his roommate, Malachi Mizrahi.
Neurodivergent and gender-fluid, Malachi wakes up each morning with a whole new personality, but one thing remains constant: his love for Nico. They clicked perfectly from day one, sharing a love of everything from anime to nature documentaries. They even share a bed. Platonically, of course.
One night, the lines blur when they share a kiss, but before things can go further, a desperate call from one of Mal’s dance students throws them into a missing person’s case that leaves them with more questions than answers. To complicate matters, Mal reveals he’s been quietly orchestrating Nico’s whole life without him even noticing. Nico is shaken to his core, his perception of their relationship shattered.
As they navigate the perilous world of a vicious Chinese triad, their bond deepens, and Nico begins to see that Malachi is not only the perfect friend, but the perfect man to fulfill all his needs. Together, they must face their past and survive their present if they want any chance of a happy ending in their future.
