After the events of season 2, they grew even closer, with Asami helping Korra recover from mercury poisoning and Korra sending her letters during the three years she spent away from Republic City. Eventually, they became friends and Asami joined Team Avatar, turning into an essential part of the group. At first, she and Korra were intimidated by each other’s presence, since Korra also had a crush on Mako. When she was first introduced in The Legend of Korra, Asami was Mako’s girlfriend and Korra’s romantic rival.
However, although there are romantic undertones to Asami and Korra’s relationship, they never shared an onscreen kiss nor declared their feelings. The last shot of the show has the two girls holding hands and smiling as they step into the portal, in a scene that is reminiscent of Aang and Katara at the end of Avatar: The Last Airbender. At the end of The Legend of Korra, Asami and Korra decide to go on a vacation together in the Spirit World - but they specifically didn't kiss.
