Energetic and lovable middle-child Karl's strengths are aplenty, but they sure don't include senior year calculus skills. Thankfully, a reserved but imaginative neighborhood boy, Sapnap, has just about the highest grade in his calculus class (not that he'd ever actually admit that, though). Quickly their friendly hangouts begin to foster a secondary meaning, as both boys start to develop feelings for each other. As Karl and Sapnap grow more and more attached, a shocking discovery takes a toll on one boy's mental health, and this leads to a strained and unpredictable relationship between the two. Will their attachments to each other be enough to conquer the realities of their adolescence nearing an end, or will forces out of their control prove to be too strong for their young love? Trigger Warnings/Content Warnings: Strong language, mental illness, physical illness
