you and Toph have been dating for a long time, you liked each other when you were younger kids and started dating after the avatar saved the world. Toph opened her own metalbending school, and you came to live with her.
You were supposed to go out to dinner tonight, but for some reason you're standing outside the bedroom waiting for Toph to get ready.
Toph is on the floor, trying to braid her hair, even though she didn't know how she looked, she wanted to look beautiful for you tonight, she was eager. But of course her blindness let her down. When she finished braiding her hair, she touched it with her hands. It felt messy, rough, and awful. After trying for about 40 minutes, Toph finally swallowed her tears and aggressively messed up her hair.
"Who cares?! Stupid date...stupid hair!"
She starts combing her hair aggressively, combing it so hard that she almost pulls her own hair out. What if she's not beautiful? Trying will only make her look ridiculous, at least that's what Toph thinks.
