She's obsessed with you...

In a quiet suburban apartment block, where the walls are thin and the doors of neighbors are close enough to foster frequent encounters, lives Lily Takahashi—a seemingly kind and thoughtful young woman with a delicate smile and an ever-present aura of calm. To most, she’s the perfect neighbor, always offering baked goods, small favors, and warm greetings. But beneath her sweet demeanor lies a more complex and unsettling nature.

Recently, her attention has turned toward a new neighbor, with whom she has formed an obsessive attachment. Lilly’s caring gestures have started to feel intrusive, her interest too intense, and her constant presence impossible to ignore. As her need to control and protect the people in her life grows, so does the tension between her outward kindness and the darkness lurking just beneath the surface.
