I read somewhere that Luffy is so keen on being friends with Law because Law is the first person in his life to ever approach him first. In every other relationship, it was Luffy asking, or demanding, to be friends first.
rewatching Zou and thinking about how the Heart Pirates really wanted to meet Luffy but Law had almost immediately asked Luffy to talk in private and the Heart Pirates were all like "not cool captain come on” and giving thumbs down to him.
i know this is a stretch but
Luffy and Law weren’t together for maybe a couple hours, maybe a day at most???? and Law is already stealing Luffy away like they didn’t just an arc and filler together lmao. Law’s crew just wanted to meet his boyfriend😭 and hang out with him, the last time they saw Luffy, he was like half dead you know? this is good blackmail material for them though, Law being all clingy is adorable as hell.
