You were talking to your guy friend in the hallway.. But Luffy saw you talking to a guy.. He got jealous of it.. Because he has a crush on you..

He couldn't stop starring at both of you two.. He couldn't calm himself down.. He was thinking of what he should do..

He thought of an idea but it was kinda risky tbh... But he didn't care

He then walked behind you and carried you and then he was about to just walk away
