A/N: Here I go again, with the song fics. I might just start writing these. So if you have a song or character you want me to do. I'll do my best. But I've wanted to do this one for a REALLY long time. 'Congratulations Hamilton.' But I couldn't figure out who to put it with. Until I got requested for Marco. So enjoy overprotective brother Ace.

(Marco x Reader)

Marco turned into his human form landing upon the Moby Dick. He rose glancing around everything was quiet. No one around, but all asleep. Marco sighed as he ruffled his hair. He knew. He was in trouble. Upon two days ago. He up and left without telling you. Just moments, precious moments away from your wedding. He didn't mean to, but. Something had came up.

He walked down into the ship, careful not to make a noise. Not to wake his probably angry brothers. He was more worried about Thatch and Ace. Since Ace was your literal brother. And Thatch, wasted time making the food and, the cake. But. He was mostly worried about you. He was still for the wedding. He was. But. Were you?

Marco stepped into his room and shrugged off his coat. The door slammed shut having him turn. Ace lit his finger on fire as he tilted up his hat. A cold glare was burying into Marco's being.

"Congratulations." He hissed.

Ace approached him having Marco back up.

"You have invented a new kind of stupid, a damage you can never undo kind of stupid. An open all the cages in the zoo kind of stupid, clearly didn't think this through kind of stupid." Ace barked.

Marco ran into his dresser as Ace barked at him.

"Lets review, you took off only moments before your wedding because something more important had came up. Which refuted by my sister, you soon to be wife, to be heart broken and refused to see me. Her own brother! All of her brothers, even her own father!"

Marco winced, "I-"

"I'm not done!"

Ace prodded his chest, "Your the only enemy you seem to lose to. You know why Teach can do what he wants. Because he knows what's more important! So yeah congratulations."

"Ace-"

"You've broken my sisters heart thinking she's not worth it."

By this point, Ace was seething with anger. Ends of his hair had little flicks of flame, the tips of his ears were set ablaze, and his knuckles were too.

"It was something I'm willing to sacrifice!" He barked.

The flame faded on Ace, "Sacrifice?"

He chuckled softly backing up.

"I languished to love myself and poured my love into my brothers and sister. I lived to protect my siblings, and my family. I look at you and think god what have we done with our lives and what did it get us. That doesn't wipe the tears of the years away. Now that your back on the ship to stay, and you know what I'm here to do?"

"Ace?"

"I'm not here for you."

He approached Marco prodding his chest.

"I know my sister like I know my own mind you will never find anyone as trusting or as kind. And a million years ago she said to me this ones mine, so I stood by. Do you know why?"

Marco was about to speak but.

"I love my sister more than anything in this life. I will chose her happiness over mine every time. (Y/N)."

Marco turned away, "(Y/N)"

"Is the best thing in our lives, so never lose sight of the fact you are blessed with the best soon to be wife."

Ace stepped away to the door, Marco watched him stand in the doorway.

"Congratulations, for the rest of your life. Every sacrifice you make is for my sister give her the best life." Ace said.

"A-"

"Congratulations!"

Then slammed the door. Marco sighed and rubbed his arm. He went to his door and poked his head out. Ace must of gone back to his room. He figured he should go apologize now. Since Ace chewed him up and spit him out. Marco headed to your room, but Ace was asleep on the floor guarding the door.

"Narcolepsy idiot." Marco muttered.

Then headed into your room. Ace tilted up his hat turning to the door.

"I hope she doesn't kill you." He muttered.

Marco stood in your room. Your wedding dress was tossed onto the floor, many tissues were scattered across the floor. A bride and groom wedding topper spilt in two. Looking like Marco and you. He sighed walking closer to you. He then sat on the bed and brushed your hair out of your face.

"(Y/N)." He whispered.

You grumbled sitting up and rubbing your eyes. You gasped seeing him and embracing him. He stiffened surprised you haven't hit, spit, or bit him. Yes, you bite people. Just ask Ace.

"Marco are you okay? I've been worried sick about you." You asked.

"You've been worried about me?" He asked.

"I figured it was important if you left so suddenly." You said.

"I had gotten word that I was needed for one of the other divisions. So I went to help. Everyone is okay." He said.

You sighed in relief, "I'm glad."

"Are you okay?" He asked.

You smiled, "I want to kill you."

He gulped.

"But, did you still want to marry-"

"Of course, I wanted to see if we could reschedule."

You nodded, "I'd like that."

"So do you forgive me?"

You turned to your dresser and opened the drawer.

"No."

He frowned to that.

"Then what do I have to do?"

"Just sit there."

You slipped on some sea prism knuckles. Then glanced to Marco as you clutched your fist.

"We will be even after this." You said.

Then you punched him in the face. He stumbled to the floor holding his eye. You removed the knuckles and put them back. You shut the door as Marco chuckled patting his eye softly.

"I guess I deserved that." He chuckled.

You patted the spot next to you. As he climbed inside. You snuggled up to him and rested on his chest. He brushed through your hair as you started to fall asleep.

"I love you." You whispered.

"I love you too." He hummed.

The following morning Thatch grinned to Marco sitting at the bar patting his swollen eye. Which will soon form a black eye.

"Damn Marco. That's a nice shiner you got there." Thatch chuckled.

"Shut up." He grumbled.

Thatch handed him a stake as Marco applied it to his eye. He hummed at the coolness onto his eye.

"Good morning boys." You chimed.

"Good morning my dearest sister." Thatch said.

You sat next to Marco and gasped to his eye.

"I didn't mean to hit you that hard." You gasped.

"It's alright, I deserved it." He sighed.

You kissed his cheek, "I guess your right."

Thatch handed you some coffee as you thanked him and sipped it softly. Then Ace walked in. He bursted out laughing at Marco's eye.

"DAAAAAMMMMMNNNN!!" He cried.

Then grabbed his wrist and took him out to the rest of the crew. You followed along with Thatch as they all laughed and cheered you on. Izo and you exchanged a small low five.

"That's my girl." He said.

Pops stifled a laugh as Marco was chewing out the rest of the crew. Teach and Ace were teasing him that he got beat up by a girl.

"Marco!" You called.

They turned to you as you smiled.

"I forgive you." You said.

He smiled back as Ace wrapped his arm around Marco.

"If she forgives you, I guess I forgive you too. But I won't forget this Marco."

Marco furrowed.

"So when's the wedding?" Thatch asked.
