both mangas recide in a mysterious shop where they give something in return for something they want.both shop owners have a animal thing as a assistant. yume kira dream shoppe is like the korean version manga of time guardian. i think that both mangas are really similar even the genres kinda match so if you like one of this manga you should read the other one.
