Thanks for the Billionaire, Mean Girl

I took my roommate’s discarded online boyfriend to pay my mother’s bills. He wanted a nursery rhyme. I sang, and his autistic nephew Kit finally calmed down. I became Kit’s nanny—he hadn’t spoken since his parents died. My songs and care brought him back. Callum, Bellmere’s richest man, fell for me. When Sloane humiliated me, he defended me publicly. On Kit’s birthday, Kit wished for me as his mom. Callum proposed.
