Author's Note: This does not have the most original title, but I did not write that many stories, so be nice.
1. Coronation
When they first met, it was at Zuko's coronation as Fire Lord. They bumped into each other during the banquet held after the ceremony. They made small talk and saw they had a lot of things in common. They made a promise to see each other again.
2. Beach
At Ty Lee's home of Kyoshi Island, Teo could enjoy the beach with her. Many of their friends were there too. Ty Lee decided to drag Teo into the water with her, insisting that if he could figure out how to fly, he could figure out how to swim. He didn't quite manage the swimming part, but found he couldn't care less if he could just spend time with her.
3. Night
At night, they watched the stars together. They could just spend hours passing the night away in each other's company, enjoying each other's presence.
4. Air
When Ty Lee first visited the Northen Air Temple, Teo showed her how to fly with the gliders his dad made. She enjoyed every moment of it, not just the flying, but also being close to Teo.
5. Beautiful
When Ty Lee showed off her acrobatic prowess, Teo was mesmerized. To him, while she was performing in front of everyone, she never looked more beautiful.
6. Fun
One of the things they found they had in common when they first met was that they love having fun. They like doing things for the sake of having fun. This is what first attracted them to one another.
7. Kiss
At a reunion hosted by Aang and Katara, they found a private spot and had their first kiss with each other there. When they returned to the party, they learned that the private spot wasn't so private.
8. Friends
Their friends were supportive and approving, but they just can't resist teasing the new couple. Ty Lee and Teo had to endure this for the remainder of the reunion.
9. Marriage
All of their friends attended their wedding. The acrobatic Fire Nation born Kyoshi Warrior and the wheelchair bound Earth Kingdom genius mechanic. It was among the best days of both their lives when they became husband and wife, and they wouldn't trade it for the world.
10. Children
They already had several beautiful children, and soon another will enter the world. When Ty Lee gave birth to a girl, Teo was ecstatic to have another child. And they named their latest child, Pema.
Author's Note: I have a personal head-canon in my head. Ty Lee and Teo got together and one of their kids is Pema, Tenzin's wife. Because of this, Jinora, Ikki, Meelo and Rohan all have heritage from each Element Nation, which I find so very awesome.
