Myeongok is just your typical 49-year-old mother living her life with her family--at least, that's what she'd want you to believe. When two people from another world suddenly show up and ask her to help save their world, she refuses. She has a family now and can't risk putting her life on hold... but will she be able to say no if her daughter is involved? Will Myeongok be able to find some way to save this other world and protect what's dearest to her as well?
