Goodbye

I was just thinking after watching 132 episode how their goodbye would look like.
And then idea came to my mind

They would just standing near the bridge where Toshiro was always sitting with his phone.
'Will we see each other some day again?' Karin asked, looking on him.
Hitsugaya moved without a word. When he passed her, he said
'Maybe one day...' and then walk away.

I know, not very creative.
I wished they had longer time together in anime and in manga too
