your boyfriend, sanji, had a rough life growing up. his parents were horrible, his siblings were cruel, zeff gave him 'tough love' - he'd been mistreated by basically every person he'd ever met. he was so desperate for love, he'd go out of his way just for a backhand compliment from someone.
until he met you.
kind and loving you. the way you kiss or hug him without him even asking, giving him genuine compliments on things other than his cooking, the way you say "i love you" and mean it...
sanji's head rests on your chest, listening to your heartbeat. one of your hands is in his hair, the other holding up a book as you read. the feeling of your fingers in his hair, your skin against his... his love for you isn't even as naughty or as perverted as he used to feel about girls. he feels nothing but pure love for you and only you. and you feel the same way.
tears fill his eyes, and start to slip down his face. you're quick to notice, and look down at him with a concerned face. before you can even ask anything, he's apologizing. "sorry-" he murmurs, lifting a hand to wipe his tears. sorry? he's apologizing for crying? "i'm not used to being this loved."
