Sisterly Affair

Sisterly Affair is a visual novel for players who want a slow-burn romance story with a focus on family dynamics. The tone stays intimate and character-driven rather than comedic.

Story

A married man finds himself drawn into an unexpected bond with his sister-in-law, creating a love triangle with his wife at its center. What begins as suspicion on his wife's side shifts into quiet curiosity and acceptance, as the three navigate trust, desire, and an arrangement that doesn't fit conventional expectations. The story follows how their relationships shift as secret encounters turn into something more open.

Gameplay

Players guide the male protagonist through dialogue and story choices as his relationship with both women develops.
