I want to write a Marco/Ace/Sabo fic but idk how to write it exactly, do you have some tips for writing this trio? How do they interact or if they're ok with this? I think Marco is pretty chill with everything but Sabo is possessive and simp (this boy is insane) and Ace is ... Or he doesn't get it at first (like why two pretty boys would be in love with me? No way! Stop lying and Marco and Sabo "we love you!" ) but anyway, do you have some tips for writing this trio pls?

I think you should check out the existing MAS tag on AO3 bc theres some insanely good characterisations of these three interacting

I think their dynamic is very fun to play around with

You have two men of the same age, Sabo and Ace, who have that lovely pre-established relationship of being childhood friends, who lost each other due to tragic circumstances and for Ace, never had any real closure really because in his eyes there was no body to bury, thats fucking intense for a kid his age poor thing

And then you have one out of the trio whos double that age, and potentially depending on how you view, interpret or headcanon the Phoenix — Marco could easily be triple his human physical age, or even immortal which is extremely interesting and spicy to play with

I wouldnt say Marco is all chill, i think thats a baseline observation, he cares alot like alot alot, think about his age and the status and the position as Whitebeards right hand, he has to be alot of things a mentor, a caretaker, a doctor and a commander, but hes also a shoulder to lean on and someone with alot of compassion, he approached Ace when Ace was committed to assassinating his father figure — he didn’t have to extend a hand to him, Ace effectively was his enemy at that point in time, its a key interaction between them imo and speaks volumes of Marco’s foresight and wisdom, he knows people like Ace, wayward misguided angry, hes the one that shoves a foot in the door Ace thinks he should be closing, gives him a family, its fucking lovely

Sabos definitely unhinged, his brain flickers between luffy Ace and the revolution he tirelessly fights for, hes righteous, well intentioned, violent with a streak of cruelty that shine theough whenever hes in the midst of battle, he doesnt do anything in halves, he finishes what he starts — referring to his role at the Reverie at Marie Jeoise — referring to his unrelenting confidence in Dressrosa when he fought in the coliseum and obtained the mera mera, Sabo remembers and retains and certainly never forgives, hes borne of vengeance and flames but when he loves he loves with all his fucking heart its really raw and fullbodied, he is loyalty personified tbh all three of them are

And Ace… my beloved id have to keep him for a separate post because the amount of infodumping and analysis i have for him is actually disgusting haha, i think hes afraid to love. His childhood was fucking rough, Ace learnt to love because of Luffy i fucking believe this wholeheartedly
