Surrender Love: MM Sci-Fi Romance (Antonello Brothers: Immortal Book 1) by Kayelle Allen

Every lifetime, Luc breaks the rule: Never fall in love with a mortal. But with this man, it could be forever... Being dumped broke Luc's heart, but public humiliation crushed it. Online betting programs placed odds on how long it would take the wealthiest man in the Empire to find a new romance. He was betting on never. When Luc signs to represent Izzorah's band, the desire that flares between himself and the catlike alien is instant and irresistible. But to yield means becoming vulnerable, and sharing secrets far too painful to reveal. Izzorah's ability to smell every emotion means Luc can hide none of his feelings. The sole thing Izzorah desires is to have a male warrior to love, a forbidden coupling on his homeworld. So he makes a sincere wish that if Luc is his warrior, the man will rescue him. When an accident occurs, and Luc donates blood to save him, what else can it be but Izzorah's wish coming true? It's clear that Luc is too hurt to surrender his trust, even though he longs to be loved. So Izzorah decides that no matter what obstacles he faces by coming out, he will put aside his fear and focus on Luc's need. Because as sure as the sun rises each day, Izzorah was made to be the shelter of Luc's heart... A closeted alien rockstar falls for his manager who is fresh out of a breakup — and immortal.
