Cynthia is a Saintess who was cursed by a witch as a child. She has only half a year left to live.

One day, she heals a dying knight named Kirill, only to be met with a sudden surprise: he immediately proposes to her.

Cynthia rejects him, knowing that her body is being consumed by the curse day by day. She assumes he will give up quickly, but Kirill refuses to back down. He visits her again and again, determined to find a way to cure her...

Bewildered by his straightforward and honest love, Cynthia slowly finds herself falling for him.
