Synopsis of Kimi wa Houkago Insomnia

It all started with the death of one of the members of the Astronomy Club. From this, the rumored ghost of the club came to life. Ganta Nakami, sleepless and grumpy, meets Isaki Magari, moderately rebellious but easy-going, in the abandoned observatory of the Astronomy Club. Magari wakes up with a start and tries to escape from the place, but a broken door prevents her from doing so, forcing both of them to enter. The two forge an unlikely friendship, which leads them to use the observatory as a safe space to mingle. Kimi wa Houkago Insomnia follows insomniacs Nakami and Magari’s time at the star observatory as they help each other cope with insomnia and the lasting effects it has on student life.
