It is December, which means that at the Kalvak Astronomical and Meteorological Center it is eternal night. Nevertheless, Kalvak remains a prestigious place of research; anyone who is accepted to research at Kalvak is guaranteeded any job they want in the field. This is in no small part thanks to AMIK, the AI supercomputer who runs the Center. When Somporn was selected, this was a dream come true; despite only starting university very recently and later in life, his extraordinary proficiency in the field made him a natural pick to study at Kalvak, along with 7 others. This dream, however, suddenly becomes sour when AMIK begins acting strangely, culminating in the computer forcing the group to exist in a timeloop until their demises.
