She was rescued by an unknown man (the owner of a mountain hotel), who happened to pass by. Several months passed, the fox's wounds healed and she felt indebted to that person. The fox wanted to repay the man for his kindness and mercy. She took on a human form and began to look for her savior. By smell, the fox found a hotel at a hot spring, which was in charge of the person who saved her. Entering it, she found her savior on his deathbed, he was about to die. His only concern was his hotel and he didn't want to talk about anything else. The fox, before his death, promises that by all means he will save his hotel from closing and restore order there. However, she understood absolutely nothing in the hotel business, and indeed in these human affairs. In search of at least some answer, she decides to search the owner's room. The fox finds a porn book about hot springs and decides to use it as a guide to action...
