Zujin is the pairing of Zuko, an exiled Fire Nation prince and firebender and Jin, an Earth Kingdom commoner and non-bender in the Nickelodeon anime Avatar: the Last Airbender. Jin sees Zuko working at his Uncle Iroh's tea shop, and develops a crush on Zuko. This leads to them going a date where Jin kisses him. It was unknown whether they ever went on another date or continued a relationship since Zuko is seen with Mai in the finale. It is not as widely known in fandom as Maiko or Zutara ships.
Fan #1: Don't you love Zujin, a prince falling in love with a commoner!
Fan #2: As if, Maiko forever!
