This is so cute! I liked how Katara picked a seashell because it reminded her of Zuko's eyes.

I love how Katara just says whatever is on her mind, and I felt sorry for Zuko when she asked him this (mind you, I also felt sorry for Zuko when he found out he misunderstood Katara's intentions):

"So," she said in a milder tone. "Do guys collect a bunch of seashells and show them off?"

I thought this line was priceless:

"In the Water Tribes, if you give someone a seashell, it means 'Here, have a seashell.'"

Do you write any other stories with this pairing?
