Asakura Shinji was at his wit’s end. Night after night, sleep escaped him. Even lying in bed with his eyes shut was no good. Instead, he’d get sleepy during the day at school, always in a haze... One evening, on a whim, he ended up going out into the town when everyone was asleep―― Shinji unexpectedly bumped into his homeroom teacher, Hagino Umi. Concerned, Umi listened to Shinji’s insomnia problem. Though he received this advice, Shinji didn’t know where to start.

Shinji, understanding this, ventured out again another night, not expecting much. There, he encountered――Umi-sensei, in a different outfit, pretending to be someone else. Thus began a string of special nights, just the teacher (?) and her student, spending precious time together, a soothing balm for his troubled heart―― Also features the after story for the previous heroine .
