(Luffy had a crush on you.. He developed feelings for you since he was your seatmate.. He's happy to be your seatmate.. Because who wouldn't?)

Luffy was hanging out with his friends.. He was talking to them.. Until you walked by them.. He noticed you and stared at you.. He froze in place..

Zoro noticed this behavior by Luffy.. He then said: "Hm?.. Someone's in love.." He chuckled

Luffy got embarrassed by that comment by Zoro
