We’ve all heard that people would do anything for their 15 minutes of fame, and up-and-coming Mukbang star, Bang Ha-Ri is no different. She was dead set on eating her way to the top until she got slammed with a doctor’s order to lose 20 kg or run the risk of contracting diabetes, coronary heart disease, high blood pressure, and so on. Determined to get back to making mukbang videos, Ha-Ri starts exercising every day after school.

Meanwhile, her classmate, On Do-Yun, has his own problems. Busy fighting his inner demons and trying to keep his urges to suck blood at bay, this half-vampire is in for a shock when the scent of Ha-Ri's blood proves impossible to resist. What makes things even harder is that Ha-Ri won’t stop offering to let him drink her blood. This unlikely pair strikes up a deal to have weekly blood-sucking sessions. But, Do-Yun can’t seem to figure out what makes her sweet-smelling blood so delicious and why she’d go to such trouble just for her career as a mukbang vlogger. As he finds the answers, he soon learns that he’s not the only vampire in town after Ha-Ri's blood… or her heart.
