The Change in Di Navarra's Plan: Harlequin comics

As with even the finest perfume, you'll eventually fade away from me.
Holly, an amateur perfumer, has scored a meeting at a big cosmetics firm in the hopes of selling her original perfume. Once in the office of the CEO, she meets Drago, a man with the kind of looks and scent that make women fall instantly in love. Unfortunately for her, the CEO is also auditioning for a new advertising campaign, and somehow she's been cast as the model! Without a moment to explain the misunderstanding, she finds herself pulled in by Drago's piercing eyes and they wind up spending the night together. And, on top of everything, the next day Drago has the gall to ask Holly to leave!
