Okay so, recap. This isn't canon, like at all so, shut up. It's also gay, like a lot, so, shut up. Toph has just joined the group teaching/protecting aang. They're all adjusting, so it's a bit difficult. This is directly before the duel at the abandoned town. Alright now that that's settled, we need a bit more info...
The entire gaang lives in one big apartment together, but when Toph invites Zuko to live with everyone, they have to learn to adjust. After getting Sokka's business shut down, Zuko tries his best to make it up to him but Sokka doesn't budge. Not until the first night Zuko moves in. What happened on that first night...

The gAang all lives together in ba sing se. Sokka and Zuko have been friends since kindergarten and after a wild party Sokka feels new feelings developing about his best friend.
