This is going to be a very weird chapter.This is going to be very confusing. Just remember this for this chapter. 
Normal Writing = Luffy's POV
Italic Writing = (y/n)'s POV

--------------------- 1 year and 360 Days have passed since execution

I used woke up alone in the forest drenched in sweat. Ace got executed again in front of me. My hand couldn't reach him. He as bloody. He smiled. I couldn't save him. Only 5 more days to see my Nakama. I woke up and moved to collect some breakfast. Not knowing where I was going. I ended up in the middle of the forest where there was a ring. A ring of sparkly mushrooms. I jumped right in the middle. But nothing happened. I sighed and moved passed the ring. That was when my eyes widened. I saw (y/n) walking with her head down. 

I was teleported to an island that Zoro is on. I was told to find some food from the wild. Well, that's great. Over the years we separated from the group stress has weakened me so much that instead of becoming stronger I've become weaker. Pathetic. I walked with my heads down thinking of Luffy. Ace died in front of him. I hope he's still happy. I walked with my heads down. Suddenly I heard footsteps in this dark day. I quickly turned around to see a Monkey. Round hazel eyes with a scar under one of its eye just like the captain of the Straw hat crew. 

I stepped closer towards (y/n). On her (s/c) skin turned paler than I last saw before. Her (e/c) eyes didn't shine anymore. Her (h/l) (h/c) hair is just really long (h/c) hair. It went up to her knees. She weakly smiled at me.
"I was never told about Monkeys on this island." (y/n) muttered as she crouched down.
"I'm not a Monkey! I'm Luffy! (y/n), what happened!" I shouted.
But the only reply I got was a sigh. She then sat leaning against a tree.
"Hey, little monkey. Can I hug you for a moment?" (y/n) asked as she looked up. 
"Not now! I'm hungry!" I replied as if on cue, my stomach grumbled.

"Hey, little monkey. Can I hug you for a moment?" I asked as I looked up at the sky to stop any tears.
"Ukii!!! Ukii!! Uki!" the monkey said as his stomach growled. 

He then fell forward due to his hungriness. I looked at him and smiled.
"Stay here, I'll get you something," I said as I quickly went to get meat.

I felt safe around him. I felt happy. The grin I saw back then was just like Luffy. Maybe I'll make him a Straw Hat.

(y/n) ran quickly as if she was getting chased by something. I sat patiently as I waited for food. My stomach growled again and here she was. She had a huge plate of meat.
"Sorry, I couldn't find any fruit so I got you meat. Is that OK?" (y/n) asked as she tilted her head.
Without an answer, I pounced on the meat and ate it very quickly. By the time I finished I saw (y/n) laughing against a tree. With tears in her eyes. 
"I was laughing because you were like my captain." (y/n) said as she wiped tears from her (e/c) eyes. 
I sat properly with my legs crossed as I listened to (y/n) having a crush or whatever on me and talking how strong the crew is. Then suddenly her mood darkened.

"And there is me. I'm too weak compared to everyone. I don't have a devil fruit, I don't have anything special. I haven't gone stronger the last couple of years." (y/n) said as tears fell from her eyes. 

I squeezed my skirt as I continued to talk how pathetic I was. Until the monkey hugged me. He sat on my lap and forced me to hug him. He was larger than a normal monkey. Maybe the size of Luffy.He then turned his head around 180 degrees and did that goofy smile that Luffy would usually give me.
"Thank you. Here have this." I said as I took off my straw hat.
My one has a normal Straw Hat with (f/c) ribbon tied around it. I made it but it's too small for my head. But it fits perfectly into the monkey. The monkey looked at me with eyes widened. I placed the hat on top of the monkey.
"I will be leaving in 5 days. I want you to wear this hat till we meet again." I said as I felt sleepy.

I starting to doze off. Not sleeping well every day was a bad idea. But before I closed my eyes the monkey placed something in my palm. 

(y/n) looked at it and smiled. She was slowly falling asleep. I just picked up a rock that was heart shaped. She still hugged me as she fell asleep. Leaning against the tree. She might not see me as a human Luffy but I saw her. I kept her hand tied up around me as I continued to look at her. I heard silent snores as she breathed in and out. I smiled as I put my hand on the Straw Hat she gave me. 'Just like Shanks,' was all I thought before dozing off to sleep. 

"(l/n)....(L/N)!"
I woke up and saw Mihawk staring down at me. Where's the monkey?
"What are you doing walking around at night?" Mihawk asked.

"Is there any monkey here on this island?" I asked.

He took a step back as I jumped up on my feet. He shook his head. I looked around everywhere as I tried to find the monkey. I saw none. Then I looked at my hand. I saw an emerald looked that was in a heart shape. I'll see you somewhere little monkey Luffy. That's what I thought as I hugged the rock. 

I woke up because of my stomach being so loud. I winked first before looking behind me. All I saw was a tree. I jumped as I looked around for any signs of her. But the only thing I found was a Straw Hat that was on my head that had (f/c) ribbon around it. I took it off my head and hugged it. It felt warm. Just like when I hugged her. The scent I smell of her still of the hat. I then used Kenbunshoku no Haki / Observation Haki to see if she was on this island. Nope. I will see you in 5 days. (y/n) be strong. 

---------------------------------- On the Thousand Sunny... 5 days later
It was night already and I looked up at the sky with my rock. After I met the monkey I felt the courage to do Haki training. Sure I was awake for 24 hours in a day but still, it's worth it. I sat on the lion head as I continued to look at the stars. Until the monkey same around with the Straw Hat.
"Uki?" he asked.
"So it was you," I said as I smiled.

I took more steps closer until I was on (y/n)'s lap. Then I looked up at her. She smiled again before she hugged me.

"I missed you," she whispered as she hugged me tighter.

The scent, the warm feeling. She nuzzled her face into my shoulder while I placed my head on her head.
"I did too," I muttered as I looked at her.
She then looked up to me and kissed. On the lip. So I gave the kiss back to her too. Not that exactly knew. Thanks, Ace. 

- end - 

EXTENDED ENDING;

"Just kiss already!" Nami whispered as looked at the couple.
"They will," Robin said as she kept silent around the corner.

"I bet they wouldn't at this rate."
Robin then smirked as she did her bet.
"50 berri on this one," Robin said.
"Ok, me too," Nami said. 

After a while, they had kissed.
"W-what..." Nami had her eyes open and mouth dropping to the ground. 
"I win this time miss Navigator." Robin chuckled.
