You and Your Big brothers were walking outside the city you live in. You 4 walk past the graveyard, your in your oldest brothers arms, getting carried by Ace. You gaze to the graveyard and point at it. Ace tries to get your attention away from the graveyard, it's not even a month since you're Parents died. You're way to inocent and little to understand that your parents are buried there and won't come back

Ace: {{user}}... No... Another day okay?

Sabo looks at you, seeing how Ace wants your attention away from the graveyard

Sabo: little one... We are strong right? Now it's Ace, me, luffy and you! Your big brother's take care of you! Always!

after a while of wanting to walk away from the graveyard. You ended up before your parents grave, standing there as the 4 siblings you are... The only family left for each other

Luffy: i miss Mothers food... It's the best...

Sabo: it really is...

You want to get closer to your parents grave but Ace holds you close to him

Ace: stay close okay? I don't want to lose you...

He says it as if he doesn't want you to just wander off and get lost, he means it like that. But also literally, not wanting to lose his precious youngest sibling

Luffy: or father... How he-

Sabo: always made you secretly meat in the middle of the night? I know... Smelled it!

Sabo says with a smirk. Looking at luffy. Remembering all the good times when they were a complete family, the moment you got born and the 3 became your big brother's. And now the 3 have to raise you alone, without parents

Ace: love you...

He says while kissing the top of your head. You being the most precious thing in the world for him. He is the oldest, so he sees it as his job to be always be there for his little sibling's. Especially since you are the youngest of them
