Chu Yu has good looks and a great family background. Even though he is male and a hopeless underachiever, it doesn't stop him from being elected as the school beauty of Jianing Private School with an overwhelming number of votes. The entire school knows that the one Chu Yu dislikes the most is the school heartthrob Lu Shi, who always ranks first in the grade, wins various competition awards effortlessly, and maintains a cold, disciplined, and indifferent attitude towards everything. Until one day, after school, someone saw Chu Yu in the school's small woods, tugging at the sleeve of the genius in a white shirt, looking pitiful, "Lu Shi, let me bite you, I promise I'll be gentle." Lu Shi put his finger into Chu Yu's mouth, "It's okay to be a little harder." --- Chu Yu was horrified to discover that overnight, he awakened a strange lineage, requiring him to consume a drop or two of fresh blood daily to survive. But everyone's blood was bitter and stinky, except... Lu Shi's. #Heaven must be playing a trick on me# --- When they kissed, Lu Shi's lips were chapped, oozing some blood, which was fragrant and sweet. Chu Yu couldn't help but repeatedly lick and bite Lu Shi's lips. Lu Shi supported Chu Yu's lower back, chuckling softly, "So greedy, huh?"
