Toph Beifong is hurt, heartbroken, and mostly left aside... The worst part of being such a rough time is seeing her Soulmate being engaged to someone else... Sokka's diamond eyes were shining only for Suki, whereas Toph's grey eyes were only crying tears for him... So instead of keep acting like she was a cold and stone hearted young lady an letting it go, she preferred to acting otherwise and end this situation, in the worst and unexpected way. Their love as frail as crystal will be birthing at the very night Sokka announced his engagement to Suki.
