After securing a job offer, our protagonist is set to leave her home prefecture in the spring. She goes to a dilapidated shrine to offer thanks, as usual, when she discovers a young man lying on the ground. While tending to the young man, who had come to convalesce due to poor health, the protagonist, not wanting to leave the sick man alone, offers to cook and care for him until spring. She is delighted to see the otherworldly young man gradually begin to smile. However, the young man's behavior grew increasingly unsettling as the days passed.

“I want you to stay with me forever.”
