The narrator wakes up to find that his teacher, Mr. sudou, has returned from his trip to the seashore. He's excited to see his old friend, but he's also a little worried that he'll have to go back to his old life in the "real" world. The narrator tells us that his trip was "full of firsts" for him, and that it was "almost sad" to be going back to the real world, but that he had a good time. He thinks that "all of the things" in his other world are "ered in sane" , and he'd rather accept the "fun parts" of his new world than "accept the bad parts" .
