"But I love you, from the moment I saw you, from the moment I met you as a child and grew up with you, I fell in love with you and until now I have cared for you and loved you"

You said with tears in your eyes but Luffy lowered his head and sighed and looked at you with an admonishing smile and put his hand on your shoulder

Luffy: But your/name-sun, I only love you as a sister or a friend! I like another girl and I love her, if I really love me, let me be with her..

Without another word, Luffy turned and went to his favorite girl Arina..
