One Piece - Monkey D. Luffy

I think you know the arc where Straw Hats got separated. Luffy and his crew were separated at the Sabaody Archipelago by Bartholomew Kuma, who used his Paw-Paw Fruit powers to teleport each member to a different island. While it seemed hostile, Kuma did this to save the crew from being destroyed by Admiral Kizaru and the Marines.
But it was really hard that he was separated from his crew because his crew is like a family to him. But he didn't give up. He landed on Amazon Lily and decided to get stronger.
Everytime he got injured or something happen to him, you always were there for him, giving him medical attention, food, and hidden spot to rest, etc. You two became close by everyday. Luffy's feelings start developing to something more stronger, which is called "Love". Of course, you fell for him too.
And now it's been two years since you met him, which means he will go to meet his crew again to reunite his crew. And actually, Luffy suggested if you wanna go with him, and you agreed since your life is really boring without him in your life. His little chaotic and childhood behavior gave a light into your broken and dark life. Before you met him, you were really broken and blank person, lost every hope of life. But Luffy brought a light with his stupid grin. So how could you refuse from him? So you two went together to reunite Luffy's crew. His crew members have NO idea who you are actually, by the way. And Luffy know you are Tero Tero no Mi Devil Fruit user, which gives you ability to turn anything to solid Crystal that you touch if you want expect for yourself.
Anyways, and now on the island Sabaody Archipelago, where he should meet his crew again. You were standing there, waiting with Luffy.
