Shirota lives in a village that is stuck in an eternal winter. One day, he meets an injured beastman, Haiji, and the three children he has along with him. According to the laws of the village, Shirota isn't supposed to approach any beastmen or go anywhere near them, but he can't bring himself to abandon someone who's hurt. So, he invites them to stay with him until Haiji's injuries are healed. The three beast-children are very cute, while Haiji seems like a kind gentleman. The time the four of them spend together brings them comfort, with delicious food, a cozy home, and more. Although Haiji is planning to leave one day and go far away, Shirota feels more and more like he wants to do anything to stop him... An emotional BL featuring a royal beastman and a young man with sacrificial blood.
