Oh GREAT question my friend
How I feel about this character
I admit that Luffy is not how I was lured in to One Piece, but now that I'm HERE, wow. Luffy is an incredible combination of selfishness and kindness that makes him a delight to watch/read.
All the people I ship romantically with this character
I primarily see Luffy as some flavor of ace but THAT SAID I am extremely into Zoro/Luffy/Sanji and possibly Law/Luffy? idk I haven't gotten to Law yet but I've been told I'm going to lose my mind about him.
My non-romantic OTP for this character
Luffy plus food obviously, but also Zoro and Luffy's relationship makes me insane even (especially?) if it's not romantic. They're each other's most important person, even if the other person doesn't know it. Genuinely crazy-making.
My unpopular opinion about this character
I don't know that I have one?
One thing I wish would happen / had happened with this character in canon.
I am only up to chapter 185ish in the manga but I am suuuuuper looking forward to any/all discussion of the Nika/Luffy relationship and what that means for Luffy in particular. Delicious. Give it to me. Only [checks notes] hundreds of chapters to go.
