Kataang

Kataang is a pairing from Avatar: The Last Airbender and features Aang (the avatar) and Katara (a water-bender). It was one of the major pairings to come out of TLA, alongside it's "rival" Zutara and was based off the friendship the two characters formed at the beginning of the program. It was obvious than Aang had a crush on her; by the end of the program it was clear that his feelings were reciprocated.
