There's just something so inherently beautiful about the way Luffy loves Sanji. Because his perception of Sanji, at the end of the day, is always "he's a good person". Plain. Simple. Easy like that. "You're just like that" is what Luffy tells him. He's just, basically, a kindhearted soul. And he could quite literally list all of his qualities, but he doesn't because he doesn't need to. Why would he do that when the best description for his cook is just saying he has a good heart? The way Luffy perceives Sanji is just so beautiful to me because, while Sanji sees himself as somebody unworthy of love and easily dispensable, Luffy sees him as the representation of kindness itself. For Luffy, food is the epitome of happiness and love. Hunger means wanting something. Eating means taking something you want. And food as a concept means being full. Hunger itself is a need your body asks for, and Luffy has never been shy about it and he takes and takes and enjoys himself until he's completely full. Sanji has been hungry his whole life but has never, not even once, thought about eating out of pleasure, but only need. His job is to cook and to serve and not to eat. And Luffy sees that as the most selfless act of kindness. To create and give food to the ones who need it and want it. Sanji makes others happy, and Luffy can't understand why he keeps depriving himself of the food (happiness) he makes. He does these things out of plain, simple kindness and without expecting anything in return, and Luffy sees that. Luffy sees Sanji's heart served on a silver platter because that's what Sanji offers him every time. And Luffy doesn't want Sanji's heart or selfless acts of kindness. He wants Sanji to be kind without harming himself in the process and actually take what he wants for once (eating). Luffy doesn't get why he keeps torturing himself and giving his everything to others when he could just share it. Sanji has so much frustration and rage and pain and sadness he won't let himself feel, and Luffy is quite literally the definition of "If you need to be mean, be mean to me" (from the song 'I don't smoke' by Mitski) and "If you gave me all the anger you can't swallow I would eat it gladly for you, just don't choke" (I just thought about this thing I'm such a poet).
