Where Happiness Begins - N S Perkins

Lilianne DiLorenzo has spent most of her life waiting for a kidney transplant, but now that her dream has become a reality, she's met with a new struggle: horrible medical debt. More than that, she can't afford the medication she'll need to take for life, and while she's successful as a content creator, she'll never be able to survive without health insurance.
After realizing his lifestyle as a famous band member had become toxic, Andrew Carter moved across the country and left everything behind, losing his friends and family in the process. Starting over has been a struggle, and the only silver lining has been his new career as a music producer. Succeeding in it is the one thing that keeps him going.
After an awkward first meeting, Lilianne and Carter realize they both have something the other wants: she has the platform to promote the band he produces for, and he has the health insurance she needs...so long as they get married. While the idea sounds ridiculous at first, they can't help feeling like it's their best option.
With the two being total opposites, moving in together isn't smooth sailing, but soon enough, they realize that faking feelings for the other might not be so hard after all. That is, so long as Lilianne doesn't learn the secrets Carter is keeping from her.
