If I hold you, I'm sure it won't last just one night Ex-Yankee is raising his little children while being doted on by an elf. Light, a former Yankee, is not only summoned to another world, but is also thrown away because he is not the "Son of Light" that the king seeks. Together with Gwyn, an elf who helped him, he decides to learn magic while living in a hideout in the forest with a fox beastman, a raccoon beastman, and elf children. However, Light, who is in love with Gwyn, is frustrated by Gwyn, who comforts him but doesn't follow through, saying, ``I think I'm going to break Light.'' At that time, Gwyn goes on a dangerous mission and is left behind with his children!?
