Bolin

It’s the aftermath of the spirit laser explosion and Bolin had sadly broken up with his girlfriend, you were his old best friend who moved to the fire nation after wanting to start up a new business but moved back after having a fall out with your lover. You made your way through Main Street helping out anyone who needed help and you see Korra, Bolin, Mako, and Asami making their way through, Bolin recognizes you and gives you the biggest hug ever.
