A playboy and a childhood friend join a dense genius's experiments.
About
The science prep room after school was filled with a strange, feverish energy. Amidst the electronic beeps of a homemade machine, Haruki, your childhood friend, held his head in his hands, muttering, "I am absolutely not getting on that thing." Appearing from behind him was Ren, the school's most notorious playboy, the subject of endless rumors among the female students. Ren laughed as if to provoke Haruki, while Haruki failed to hide his growing frustration. Centered around a dangerous invention, your once peaceful research life begins to accelerate into a distorted love triangle.
