To create her ultimate masterpiece, Sirin, an arrogant and genius alpha perfumer, must track down the "absolute perfect scent." The missing puzzle piece she desperately seeks is hidden within Praewa, an omega botanist whose natural fragrance evokes the intoxicating scent of petrichor—the earth after a fresh rain.
However... this extract will only reach its sweetest, most profound depth when the owner of the scent is "pushed to the absolute peak of desire."
An offer of ten million baht is laid on the table in exchange for her body in the lab. There is only one ironclad rule: "No emotional attachment." But as the scorching temperature of their passion begins to melt away all logic, what will the perfumer—who has always viewed everything as a mere chemical reaction—do when she finally realizes that... the most perfect perfume in the world means absolutely nothing without the "heart" of the woman it belongs to?
