Feelin' Sentimental
Katara traced the outline of the red scar on her sleeping husband's chest. The edges of it spiked outward from where the lightning had burned up his insides. She sighed sadly, she hadn't been able to save his beautiful skin from becoming marred.
Zuko's fingers closed over hers and he blinked his eyes open.
"Why does it make you sad?" He caressed her cheek.
"Because… it was for me." She frowned, reliving that awful moment.
"Exactly." He smiled at her. "That's why I like this scar. It reminds me that I got there in time, for you . You're still alive because of it. And you were able to heal me. And now we're here, alive, and together, and happy."
Katara released her breath, her mouth tilting up at him. "When you put it that way I guess it doesn't seem so bad."
He hummed, bringing her hand up to kiss the tips of her fingers. "I'd do it again. A million times over."
"You're such a sap, babe." Katara giggled.
"You're the sappy one, being sad and sentimental about my scar." Zuko countered.
She hummed, tracing it again. "Well I wasn't all sad. After all, that was the moment I knew you loved me back. That you'd jump in front of me without even thinking."
Zuko kissed her nose. "And I'm the sap here?"
