You should. You really should if you are a fan of romance and shenanigans, as well as some drama here and there. And you really should if you find Chitoge funny. 

[@Krinos Solstice] After watching my first anime in Japanese, I haven't been able to go back. Now everytime I watch one in english it just feels kind of... unnatural, I guess. 

I can't stand the Japanese voices for Dragon Ball, Digimon or Pokemon, though. I started watching them in Spanish when they were on the air in Mexico and now seeing it again with the Japanese original voices just feels wrong.
