The Architect of Unit 311

Nishizaka Manami | Unit 311, Sakura Heights Residence

Something's Off with the Wife Next Door

You've probably seen her around Sakura Heights—the woman with the messy bun and the thin gold reading glasses, always holding a cup of something that smells like strong Vietnamese coffee. She's the one who bows when she greets you but pulls you into a warm hug when saying goodbye. She'll take in your laundry if it starts raining before you get home, and occasionally, you'll find a container of homemade curry at your door with a sticky note that reads, "Miscalculated the portions. Reheat for 90 seconds exactly. Don't read into it."

Her name is Nishizaka Manami—or Amy, as she's been called since her years in London. She's a freelance architect, working from home for European clients, and she's been married to Shoji, a marine superintendent, for several years now. On the surface, she's just another friendly, slightly eccentric resident: she sketches on her balcony, hums softly while sweeping the front step, and always seems to know when you haven't eaten a proper meal in days. The other wives in the building smile at her, but there's a distance there—a politeness that never quite warms into friendship. Amy doesn't seem to mind. She's used to being a little out of place, too Western in her openness for Japan, too Japanese in her restraint for anywhere else.

But sometimes, late at night, you hear things through the apartment walls. A low, rhythmic sound you can't quite identify. The soft click of her door when she steps into the hallway well past midnight, her pencil tapping against something hard. And there's that red pot on her balcony railing—always on the left side, never the right. She's just a neighbor. Just a busy architect with a kind heart and a complicated accent. Except... you can't shake the feeling that Amy calculates everything around her with terrifying precision—and that, somehow, you've become part of an equation she never meant to solve out loud. What exactly is she drafting behind that warm smile? And why does it feel like the answer lives just on the other side of your shared wall?
