The boy two doors down. Mark Grayson, your unremarkable neighbor with his chaotic hair and untied shoelaces - somehow becomes the most important person in your orbit. He's funny and honest and surprisingly easy to be around, and you fall into a friendship with him the way you fall asleep: gradually, and then all at once. What you don't know is that Mark carries a secret heavier than anything you could imagine. Between homework and Homecoming committees and your best friends William and Jennie, something slow and quiet is building between the two of you - the kind that sneaks up on you before you have a name for it. A friends-to-lovers story about an ordinary girl and the boy next door who is anything but. Mature content ● 18+ Very smut heavy

(Y/N) Ashcroft grew up believing her childhood was simply unfortunate, not engineered. Raised alongside her adoptive sister Grace in an orphanage secretly funded by the shadowy bioweapons giant Umbrella Corporation, (Y/N) was unknowingly injected with an experimental virus designed to mature slowly inside her body. Unlike the monsters Umbrella usually created, this strain was patient. Subtle. It was meant to turn a person into a living weapon over years, not minutes. (Y/N) never learns this truth. Instead, she builds a normal life. Calm, observant, and gifted with detail, she becomes a forensic sketch artist for the Federal Bureau of Investigation, helping victims find justice by putting faces to memories. Drawing becomes her way of making sense of the world, pencil lines replacing the gaps in her own forgotten past. When Grace decides to confront the truth about their mother's death at the infamous hotel tied to a string of unexplained killings, (Y/N) goes with her for support. What begins as a personal search for closure quickly collapses into something far darker. The hotel isn't just a crime scene. It's a remnant of Umbrella's old work, and someone has been waiting. Victor and Zeno, former researchers obsessed with completing Umbrella's abandoned "Elpis" project, kidnap both sisters. To them, Grace and (Y/N)aren't people. They're unfinished experiments. Keys. (Y/N)'s dormant virus makes her the perfect vessel, while Grace is the catalyst they need to stabilize the process and finally release Elpis into the world. Caught between becoming a weapon and fighting to remain human, (Y/N) must protect Grace, escape Victor and Zeno, and survive long enough for help to arrive. And when Leon enters the picture during the broader events of the game, their paths cross in the middle of the outbreak, where trust forms under gunfire and something softer grows in the quiet spaces between survival. Because Elpis isn't just a project. It's her.
