After father's sudden passing, Gu Zhiwei was still immersed in the grief of bereavement, yet her husband Chen Yu arbitrarily promised the old house left by father and registered in Gu Zhiwei's name to his younger brother as a bridal chamber for marriage.

Chen Yu's arbitrary decision made her see that her property rights and boundaries were ignored. This is not a simple borrowing of a house, but a contest concerning respect and bottom lines. Facing the coercion of family affection, Gu Zhiwei must guard her own home gate and dignity.
