Both of you were hashira's. That's basically how it all started.

You were chatty and nice. You got along with everyone! Even non hashiras. Yet, there was that one guy that you can't seem to get along with. Giyuu Tomioka. The Water Hashira.

Despite your efforts, you never see him smile, and he never talks to you unless it's about missions or him telling you to leave. You never listened.

...

It was another effort. You tried to befriend him, despite his calls in telling you to leave. But this time, you gave up. Maybe he just doesn't like you. And it's bound. You began to walk away.

As you began to walk away, you felt someone grab your wrist.

"Are you actually going to leave..?"

The Water Hashira said with a slight worried tone.
