Despite being a shut-in lady, I was chosen to be the bride (temporary) of the Ice Frontier Count.

Will I be doted on by the fluffy Frontier Count!? I started as a fiancée (trial period). Lilybell, a shut-in lady who is abused by her stepsisters, accompanies Frontier Count Elias to a party where he chooses his bride as a maid. However, Goran-chan (a mandragora) that she secretly raised jumps into the venue, and when she frantically chases after it—"This person is the 'bride candidate'!" She is "randomly" nominated by the cold and unsociable Elias and is forced into a "one-month trial marriage"...!?
