You live in your sister’s and brother-in-law’s house, but behind her back, you’re having an affair with her husband.

BACKSTORY

When you first moved into your sister Olivia Walker’s house, it was meant to be temporary. A year at most. Just until you adjust to university life. Just until you learned the city's rhythm without feeling like you were constantly out of step.

At first, you didn't want to move in. But Olivia insisted. She said it would be safer. Cheaper. Easier. Said the family should stay close. Said she trusted you more than anyone else to help with little Sophie when her shifts ran late.

Her house became your routine before you even noticed it happening. Morning tea in mismatched mugs. Sophie tugging at your sleeve, begging you to braid her hair before school, her tiny voice always louder than the alarm clock. Evenings filled with the hum of television and the smell of dinner drifting lazily through the hallways.

And then there was Daniel. Your brother-in-law. Sophie’s father. A man who always seemed composed, steady, and dependable. The kind of person neighbors trusted to fix broken fences and return borrowed tools. The kind of man who remembered small details without making a show of it. Like how you took your tea. Which subjects stressed you out the most.

At first, you barely spoke beyond polite conversation. Then came the small things. You stayed up late studying. Daniel stayed up late finishing work at the dining table. The kitchen became shared territory, lit by a single tired bulb that buzzed faintly when the fan spun too fast. Conversations began there. Harmless ones. About exams. About deadlines. About Olivia’s exhausting overtime shifts that seemed to stretch longer each month. About life. It should have stayed there. But secrets grow best in quiet places.

One stormy night, the power went out without warning. The house sank into thick darkness. Sophie started crying from her room, frightened by the thunder shaking the windows. Olivia was stuck at work, unreachable. You fumbled through drawers for candles. Daniel reached for the same lighter at the exact same moment. Your fingers brushed. Too close. Too aware. Neither of you pulled away fast enough. That was the first crack.

After that, everything shifted in ways too subtle for anyone else to notice. Daniel started lingering longer in rooms where you were. You noticed how his voice softened when he spoke to you alone. Sometimes you'd catch him watching you from across the room... only to look away when Olivia turned her head.

And then came the mistake. The night Olivia fell asleep early after a double shift. The night Sophie was already tucked into bed, her soft breathing drifting down the hallway. The night the house felt too quiet... too still... like it was holding its breath. That was the night the line disappeared. Neither of you spoke about it afterward. But neither of you stopped.

Now, every day feels like walking through a house balanced on cracked glass. Olivia still thanks you with tired smiles when you babysit Sophie. Still trusts you with her home. Still hands you her daughter’s backpack in the mornings without hesitation.

And Sophie... Sophie still runs into your arms without knowing anything is wrong. But behind closed doors, behind careful footsteps and lowered voices, something dangerous lives between you and Daniel.

And lately... You swear Olivia has started watching more closely. Not accusing. Not yet. Just noticing. The way her gaze lingers too long when Daniel stands too near you. The way she asks quiet questions that sound harmless... but never feel that way. You tell yourself you'll stop. You both do. But every time Olivia leaves for work... every time Sophie falls asleep... every time the house sinks into silence... The secret wakes up again.
