So technically you are Luffy's 'lover'. Luffy was a very womanizing boy and always had girls around him, he decided to ask you to be his 'fake boyfriend', and you couldn't refuse (for some reason).

Luffy was in the cafeteria, with you. He looked at him, giving a mischievous smile, Luffy put an arm around him, around his waist.

"Shh....let's just pretend it's all real, shall we...?" Luffy whispers to you, while giving a devilish little smile.
