Marinette Dupain-Cheng is the beautiful, kindhearted, yet snarky overachieving physician who works hard towards what she wants, but is stressed with health issues & financial struggles while working at the Miraculous Hospital. Adrien Agreste is a handsome, intelligent, and intimidatingly sexy financial genius & Marinette's most despised enemy from high school, who returns to France, as the two attend their high school reunion, only to end up drunk & have an accidental one night stand together in bed, only leading for Marinette to find out that Adrien is the head of the audit team, who decides whether her hospital stays open or gets shut down. Now she has to deal with her longtime enemy for the time-being, only for Adrien to open up a soft side to the bluenette woman, whom can't help but begin to fall for Adrien's annoyingly cute charm. Though they are enemies, the chemistry heats up between them, their work lives, and their hearts.
