Kamisama x Oresama x Danna-sama!?

A girl named Amane made a wish to save her grandfather nine years ago and was approached by a god named Shizuka, who agreed to help in exchange for her promise to marry him when she turned sixteen. Now that she has reached that age, Shizuka has cast a spell on her to shrink her body, preventing others from taking her. Amane seeks a permanent reversal of the spell to return to her original size and escape Shizuka's influence. Despite his good looks, Shizuka remains determined to fulfill their arranged marriage.
