七倉園子是一名高中三年級學生，他繼續上高中。 我的大部分同學都繼續上學，所以我毫無疑問地努力學習入學考試。 另一方面，大口涉在工作的同時進入“兼職系統”。 我的夢想是像我已故的父親一樣在天文台工作，但對於沒有學費的Wataru來說，即使參加高考也很遙遠。 有一天，這樣的兩個人相遇了。 趕著離開學校的園子與在正常時間來學校的渡發生了碰撞。
Sonoko Nanakura is a third-year high school student who goes on to high school. Since most of her classmates go on to school, she has no doubts and is working hard to study for her exam. On the other hand, Wataru Okouchi goes to the "part-time system" while working. His dream is to work at an observatory like his deceased father, but for Wataru, who lacks tuition fees, even taking a college entrance exam is far away. One day, such two people met. Sonoko, who hurried to leave school, collided with Wataru who had come to school during the regular hours.
