- this is all rather repetitive but UGH im sorry i couldnt not think more abt yandere luffy
he gets so jealous so so easily. hes so needy and starved for your attention and touch that he really cant comprehend the idea of you not giving both of those things to him. he will fiddle with your fingers, playing with them as a way of keeping skinship. he will lay his head on your lap or shoulder, taking up as much space as possible.
hes so possessive over you, the fact youre his crewmate is what really drives this possessiveness. why are you giving other people the time of day when youre his? hes your captain so pay attention to him already!!! likes pulling the captain card for no reason, "as your captain!!! you need to come cuddle with me now :3"
he will pout (like really, really pout - his bottom lip glistening with saliva and jutted out as he beggingly looks up at you) and whine audibly (voice trembling and everything, going up and down in pitch to convince you to listen to him), attempting to drag you off. and when those innocent actions arent enough he starts getting pissed. he gets angry at whatever is taking your time away from him - even if its another strawhat. he will glare, but for the most part sticks to glaring. if its a complete stranger though, thats kind of free game for anyone
"fuck off!!" he would suddenly shout, getting in their personal space and intimidating the fuckkkk out of them. "leave us alone!"
and then obviously no psychopath would try crossing luffy, so they run away with their tail in between their legs. and then luffy goes back to being cheery and all smiles. he shoots you his signature grin, buries his head in your neck and shoulders while hugging your waist, murmuring in a very very very happy tone, "mine, mine, all mine, hehe"
very unsettling especially with his usually cute exterior.
loves kissing and hugging you. its all so sloppy and its more saliva than anything, but to him its his favorite way of staking claim as yours and you as his. leaves his mark too. its not really something that is sexual to him, unless he wants it to be. beacuse for the most part it just plays out with him sitting on your lap and forcing your mouth onto his neck, pleading for you to mark him up. so he can confidently parade it around for everyone to see.
he interprets the civilians that stare too long as being intrigued in his relationship status and rushes over to them, explaining how his boyfriend marked him up as his and how he is very happily in a relationship. he is so sporadic when he talks, expressive as he uses his hands to point at all the places on his body you left your mark.
luffy also gets you guys in trouble a lot with marines when the crews supposed to be "secretive" due to their high bounties and then the first thing he says is: "hi! im monkey d. luffy and gonna be king of the pirates. this is my boyfriend [name] and hes my treasure!!!" with a really wide grin on his face. not even acknowledging how he exposed you guys as pirates.
soft yandere luffy is innocent 98% of the time, the last 2% are when someone pisses him off by taking up too much of your attention and he needs to release some frustrations. he just wants your love and attention and your time and your affection and your love and your hugs and your kisses. he wants you all the time <3
