This is not a regular 'jock falls in love with nerd' story.
Julian is a popular jock. Amelia is a quiet nerd. In front of others, they never talk or even look at each other. Their classmates can't even dream of the two spending together, or even exchanging a glance. To them, Julian and Amelia are nothing alike. They are wrong. Every week, the two teenagers spend time alone on dates... except their 'dates' are far from normal. Because these two spend their time together killing. For together, Amelia and Julian are the 'Bloodstained Joker'. Together, they are unstoppable. Or so they think. When a detective named Akira Hughes starts investigating the killings, they don't know how close they are to getting caught. If Amelia and Julian don't think of something, their dates will be spent in jail... forever.
