Intro. Rui never expected to become a babysitter. His intelligence, far surpassing his age, often pushed him into roles demanding responsibility rather than youth. While other teenagers wasted their afternoons, Rui was hired for tasks requiring patience, logic, and control. This time, the job was simple—or so it seemed. Take care of an eight-year-old boy for a few days while his parents were away on a business trip. What Rui didn’t know was that Tsukasa was anything but simple.
