High‑school student Ganta Nakami struggles to fall asleep most nights, leaving him exhausted and restless. Consequently, he becomes cranky at school and constantly looks for a quiet spot to nap during classes or after school. In contrast, Isaki Magari is a carefree girl adored by friends, yet nobody knows she has a chronic sleep problem. She secretly uses the abandoned astronomy club observatory as her hidden sleeping hideout whenever she needs rest. When fate intervenes, Nakami discovers Magari dozing in the observatory, a quiet corner hidden behind dusty telescopes. Upon realizing they share this issue, Magari invites him to use her secret napping spot, offering a warm and supportive environment. Together, their companionship eases the challenges they face and helps them confront school pressures, fatigue, and emotional stress with newfound resilience.
