This all sounds magical. I really love the idea of Masaomi signing up for manliness efforts in an effort to appease Toph--and it'd probably work, even if she didn't indicate so at first. She just has to give him a hard time, you know? But eventually eventually--like you say, after a few years of him and Katara falling for each other--Toph could come to accept him as a good guy for her. The good-natured teasing will never stop, but she at least will be more welcoming towards him. Especially as his flirtatious nature becomes more subtle.

And I love the idea of her getting her hands on his poetry, heehee, though she'd need a co-conspirator to even read it out loud for her. Maybe Sokka or something. :|a
