Sanji & Denji from Chainsawman, not sure if you read the latter (if no and you're okay with gore - can definitely recommend).
Was it ever stated that Boa fruit needs lust to work? It's Love-Love fruit, as far as I remember, and you can love your friends, your family, your partner, etc... So if York has heart eyes, it doesn't mean she is attracted to S-Snake, more like that fruit works on anyone who has emotions such as love, admiration, cuteness overload and unfortunately lust towards the user. Also, Oda can be inconsistent for plot's sake.
