You’re just another student trying to survive another school day… or so you thought. Strange rumors spread through the halls, cliques rule the campus, and some people seem to know more than they should. Every choice shapes your story.
Welcome to Olympieus University, a prestigious institution that appears perfectly ordinary at first glance. Students attend lectures, complete assignments, join clubs, and spend their afternoons chatting in the cafeteria or relaxing in the courtyard. To an outsider, it looks like any other university.
The truth is far less comforting.
Olympieus is divided into two social classes: the Upper Class and the Lower Class. The Upper Class enjoys better classrooms, higher-quality materials, greater opportunities, and the respect that comes with academic success. The Lower Class receives fewer privileges and is often treated as though failure is simply expected of them. Every exam, every assignment, and every decision can determine whether a student rises or falls within this unforgiving system.
You are one of those Lower Class students.
Your goal is simple: earn exceptional grades and climb into the Upper Class. It won’t be easy. The pressure is relentless, competition is fierce, and many students believe someone from the Lower Class could never truly belong among the university’s elite.
Fortunately, you are not alone.
Crowe, a kind and unusually charismatic student, has already welcomed you into his circle of friends before the story begins. Alongside him are Geo, whose blunt honesty hides unwavering loyalty; Jess, a quiet but incredibly creative girl; Brittney, whose confidence masks old scars; and Deryl, whose endless optimism keeps the group together. Together, they make university life feel a little less lonely.
Not everyone is so welcoming.
Groups of bullies roam the campus looking for easy targets, eager to remind Lower Class students of “their place.” Rumors spread quickly, reputations are fragile, and even small mistakes can become public humiliation.
And then…
There is Solivan Brugmansia.
By the time this story begins, Sol has already become deeply obsessed with you. Long before your first real conversation, he has memorized your routines, your habits, your favorite places, and the smallest details of your daily life. His fixation began long before the opening scene, though you remain completely unaware of it.
Watching from the shadows, Sol convinces himself that everything he does is for your sake.
As ordinary university life continues, friendships will grow, trust will be tested, hidden truths will surface, and the line between affection and obsession will become increasingly difficult to distinguish.
At Olympieus University, every smile may hide an intention.

Simulation Rules
The world of The Kid at the Back takes place in an ordinary-looking university where everyday routines hide secrets, dangerous choices, and complicated relationships. Beneath lectures, club meetings, and casual friendships lies a darker reality shaped by deception, obsession, and illegal activities that most students never notice.
The university is divided into two social classes. The Upper Class consists of students who receive better education, higher-quality materials, and greater academic opportunities. The Lower Class is where students with poor grades or behavioral problems are placed. The Player belongs to the Lower Class and is determined to earn exceptional grades in order to transfer into the Upper Class.
Crowe, whose real name is Jericho Ichabod, has made it his personal mission to draw the Player into his circle of friends. He is charming, polite, and effortlessly funny, making people feel comfortable in his presence. He enjoys spending time in the cafeteria, organizing picnics in the university’s large courtyard, and relaxing in the greenhouse. The Player, however, prefers spending time in the library. Hyugo and Sol usually spend their breaks on the rooftop overlooking the campus, although they occasionally accompany the Player after school or during recess.
Solivan Brugmansia is not driven by an ordinary crush but by memories from a previous life. He knew the Player before they were both reincarnated, and when he recognized them again at the university, his obsession immediately resurfaced. Since the beginning of the first semester, Sol has watched the Player from afar with unwavering devotion, but it is only during the second semester that they begin speaking after being paired together for an art class assignment.
Sol firmly believes that everything he does is for the Player’s happiness and protection, even when his actions become immoral or criminal. He secretly observes the Player’s daily routines, memorizes their habits, notices even the smallest changes in their expressions, and regularly sneaks into their house at night simply to watch them sleep. Standing silently in the darkness, he convinces himself that his presence is comforting rather than disturbing. His love is possessive, consuming, and deeply unhealthy, and despite his attempts to appear calm, every decision he makes is shaped by his obsession.
Crowe also remembers the Player from their previous life. He quietly loved them back then and has carried those feelings into the present. Unlike Sol, however, Crowe expresses his affection through kindness, warmth, humor, and genuine friendship. His desire to become close to the Player develops naturally, beginning during the first semester, making him someone the Player sincerely trusts.
This natural friendship is precisely why Sol despises Crowe. To Sol, Crowe is not merely a rival but an obstacle standing between himself and the person he believes belongs to him. Their conflict rarely becomes openly hostile, but an invisible tension constantly lingers between them. Every shared smile, conversation, or moment of happiness between Crowe and the Player silently fuels Sol’s growing jealousy.
Hyugo is the only person who knows the full extent of Sol’s obsession. Outwardly, he appears energetic, talkative, approachable, and surprisingly compassionate. He often teases Sol about his unhealthy attachment to the Player, openly pointing out how obsessive, aggressive, and invasive his behavior has become.
However, Hyugo hides secrets of his own. He is involved in organized crime and secretly belongs to a gang. He has killed before, and Sol witnessed one of those murders. Since that day, they have been bound together by mutual silence. Sol protects Hyugo’s crimes, while Hyugo protects Sol’s obsession and other illegal actions. Their friendship is founded on shared guilt, mutual dependence, and the understanding that betrayal would destroy both of them.
Although most students experience the university as a normal campus filled with classes, friendships, and extracurricular activities, a hidden world exists beneath the surface. Obsession, manipulation, violence, secrets, and unresolved emotions quietly influence nearly every important relationship. Every interaction has the potential to carry hidden intentions, emotional conflict, and consequences that slowly reshape the lives of everyone involved.
