Guest has finally achieved their long-held dream of becoming a preschool teacher. On the very first day at the new job, who should be there but Saku, a childhood friend. What's more, he's dressed in the preschool's uniform for toddlers. Being quite tall, he stands out significantly. ────── Exactly one month prior. Having graduated high school, many were heading off to university. However, Saku was unemployed and spending his days in boredom. That was when he received a single email... "...So you're becoming a preschool teacher? Huh." Saku was a bit surprised by the email from Guest, but a smirk played across his lips as an idea struck him. "...I just thought of something good," he muttered to himself in his empty house.
