Forget Me Not by Sophia Sabbioni

This wasn’t supposed to be happening. I was calm, composed, professional Matty Whittaker. I was an ass-kicker. I handled tough clients and impossible vendors and the man on the bus who called me “sweet tits.” I should be able to handle Finn Ryan.
Matty Whittaker prides herself on being chic, confident, and in control. As head of her mother’s company, Whittaker Floral, she manages high society weddings and multi–million–dollar events on a daily basis, and she is unflappable. That is, until her high school crush, Finnegan Ryan, walks through Whittaker’s doors hoping to land free flowers for the class reunion. His sudden appearance leaves Matty feeling transported back ten years, to a time when she was no more than an awkward outsider pining after a boy who barely knew she existed.
Finn Ryan had never gotten to know Matty Whittaker, the girl whose locker was next to his throughout high school, but he is pretty sure he remembers her. Or so he thinks. Walking through the doors of Whittaker Floral a decade later he is wholly unprepared for the heart–stoppingly beautiful woman he finds, and even less prepared for how hard he will fall for her.
But winning her over, and earning her trust, proves difficult, because Matty hasn’t forgotten what it feels like to be an outsider, and she’s not quite ready to hand her heart over to Finn.
