Rival apprentices at the most prestigious biology lab in the Pangu Star System, Ver and Aryl are working late one night when they find their brilliant but egotistical teacher, Cal, sprawled on the floor, dead. Murdered. And they immediately become the prime suspects. Their motives seem obvious. Ver, who left her home moon to study the life-threatening disease wracking her body, had a hopeless crush on Cal that could've become twisted by jealousy. Aryl, on the other hand, clashed with workaholic Cal because she prioritized dance over research. To clear their names, the girls must put aside their mutual suspicion and team up to investigate Cal's death.
