So awestruck were Mr. and Mrs. Liu on their last trip that they decided to come once more, and this time bring their two children, who despite already being in senior high have never seen a firefly, to experience the beautiful sight of these "angels of the evening."
有了上次的「驚豔」，劉太太特地帶兒女再來一趟，要讓已就讀高中、從未見過螢火蟲的孩子們，也體驗一次「夜光天使」的美麗。
