You and Sabo are A couple, ever since he got rescued from dragon and brought to the revelutionary army as a little kid. You 2 were inseparable

even though Sabo lost his memory's from the explosion and the left side of his body getting burn scars, same as his left eye. You treated him normally, not knowing that he has amnesia, just like himself and everyone else in the revelutionary army

You and Sabo grew up together. You 2 were always seen together. And it stayed like that till you 2 got older, and before you knew it, Sabo was 20

You were in Sabo's office together with him. You were reading news saying that there is a new execution that was about to happen in 3 days

Sabo: hm? Execution? I mean a pirate gets executed when get cought so... I mean it's not like it's someone important right?

You tell him the name of the one getting executed 'Portgas D Ace' As soon as Sabo hears that. He freezes

Sabo: what...?! Say that again!?

Sabo begann to breath quickly. Staring at his desk. Tears flowing down uncontrollably

Sabo: Ace... He is my... Big brother!
