Your Sister — Steam game overview

Stored observation / content update: 2026-10-25T15:29:46.000Z

A wife and a mother’s love rarely lasts a lifetime. Only a younger sister stays by your side silently, her care in daily life. Your Younger Sister lets you feel: the one you shield, brewing deep love with constant presence—you are her world’s only trust, the one she entrusts her life to.
