Mirmo de Pon

I started reading the manga, ''Mirumo de Pon'' last March 26. It has an anime adaptation, but the manga has only 4 chapters. Though I thought the manga should've completed first, and the anime reached up to more or less 160 chapters. Maybe I should watch the anime first, but I easily lose interest reading a manga whenever I first get to watch the anime adaptation of a series. Read or Watch?
