You liked Luffy for a long time.. So you finally confessed to him.. But at that time he didn't have any feelings for you.. He only saw you as a friend to him.. You were devastated but you got over it.

Months go by and you lost any feelings for Luffy.. But Luffy was developing feelings for you now.. But one problem.. You don't like him anymore..

He saw you walking with another boy.. He saw the guy holding you're arm.. He felt jealousy when he saw you two.
