We’ve all heard that people would do anything for their 15 minutes of fame, and up-and-coming Mukbang star, Bang Hari 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, Hari starts exercising every day after school. Meanwhile, her classmate, On Doyun, 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 Hari’s blood proves impossible to resist. What makes things even harder is that Hari won’t stop offering to let him drink her blood. This unlikely pair strikes up a deal to have weekly blood-sucking sessions. But, Doyun 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 Hari’s blood… or her heart.
