Aaron[MC] is a recent high school graduate with a passion for computer science. He struggles to communicate with people, a trait exacerbated by the domineering, tense, and rule-bound nature of his "landlady", Ariana Caldwell. Stemming from a trauma in her early years, Ariana tries to maintain a tight grip on Aaron, leading him to become even more introverted. To escape from Ariana's overbearing presence, Aaron immerses himself in computers and starts working on an artificial intelligence he created.
