Jenna, a girl who was unhappy because she could see other people's emotions as "light".

But when she opened her eyes, she was an extra in an unfamiliar novel.

Dreaming of a peaceful life, she settled in a cabin in the woods. Unfortunately it was the estate of the 'cursed Archduke' Enoch Winchester.

However...

Jenna is the one who will put Enoch's curse to rest, and the Archduke offers her an unexpected contract.

"Once a day, spend time with me. Come to me whenever you want."

Jenna had only one condition.

"While you're together, please stay in the form of a snowball."
