This is about a 15-year-old Japanese boy named Takahiro Mamoshiru whose brother left to study abroad in America, they were really close so he got a little depressed. HIs parents got worried and decided to sign up for the "Exchange Student" program, and end up getting a strange 15-year-old American freeloader named Jason Matt Matthews (his mom calls him Jason but he likes to be called Matt), who becomes Takahiro's best friend and perhaps later "love interest"? -__- i hope u enjoy.
