A "human" decided to start a life of seclusion by moving into the forest. Shortly after entering the forest, he happened to rescue an elf in distress, and the elf, named Hinata, became fond of him. They parted ways with a promise to meet occasionally. However, that very night, a visitor arrived at the mountain hut. Initially, thinking it was the elf from daytime, the human attempted to reprimand the visitor, only to discover it was another elf named Konomi. Konomi enjoyed the pleasant punishment and also grew attached to the human.

The next morning, Hinata also arrived, and two adorable elves settled beside the human. When Konomi and Hinata went out to search for food, they were intercepted by a hostile elf named Ibara, who intended to bring them back. According to Ibara, the boundary between the elf world and the human world weakened due to a lunar eclipse.

The human, who had previously helped a dark elf named Tsukiyo, enjoyed interacting with the elves and reading the books left in the mountain hut. However, he learned that on the night of the full moon, the boundary would be restored, and the elves needed to return to their original world. Having discovered that the indigenous inhabitants of the mountain hut were also studying elves, the human followed their research and ended up living with the elves.
