After losing her mother, Y/N starts falling apart in ways nobody around her fully understands. What begins as grief slowly turns into something darker: sleepless nights, emotional outbursts, growing distance from the people she loves, and a secret dependency she convinces herself she still controls. Lucas — her boyfriend since high school — notices the changes immediately. But no matter how hard he tries to reach her, Y/N keeps pushing him out, terrified of what will happen if he discovers the truth behind her unraveling.
