Author's Notes: Hey guys! I just felt the need to write this the second it came to me. To answer a question I've been getting, yes I do take requests for one shots sometimes, if I have the time. One thing though, it has to be a Starco request, it has to be a head cannon, not an AU, and it has to be safe to read. I generally don't like doing sad ones and I'll probably have a higher chance of doing yours the fluffier it is. Well, I'm just going to stop talking now and let you read lol.

Enjoy the fic!

Hey. I'm Marco Diaz and today I'm going to teach you on how to be a bad boy.

I know you've probably heard those dumb rumors about me being "a nice guy" and all that Star's been spreading around, but trust me, I'm the best guy to talk to on something like this. Don't be fooled by those guys like Oskar or Tom (Whose been trying to kill me ever since Star left him at the Bloodmoon Ball. I mean seriously, what's wrong with that guy? What did I do? It's not my fault that Star left him in an ice cube because he lost it.) that only act like bad boys. Their just wannabes, unlike me; I'm the real thing.

Yeah I know you've heard some people call me "the Safe Kid" or whatever but that's totally not true. Just because I wore a helmet one time in the gym showers doesn't qualify me as safe! Not wanting to get hurt and being too safe are two way different things. I could've slipped and broken my head or something then I wouldn't be writing this guide! Trust me, I'm like the craziest, most dangerous guy at this school.

What? You want proof? I hang out with Star everyday. Enough said.

Now let's get down to business.

Step 1. Wear hoodies.

That's right. Wear hoodies. Why do you think I wear hoodies all the time? (Aside from being comfortable)

To be a bad boy, you got to look like one. Hoodies help a lot with this, especially when the hood is on. When you walk through a street and you see a guy with a hoodie, you want to avoid him right? I got that same reaction when I accidentally walked into the girls bathroom. Yep, they all ran away screaming, probably because of how dangerous I looked. And you know what? I did all that without my hood on. Only true professionals can pull that off.

Now watch and learn from the master. And take some notes while you're at it.

*Narration*

Marco walked downstairs into the living room where Star was currently watching TV. He had a confident smirk on as he put on the hood ofhis hoodie. Star saw him everyday with the hood off, so he had to up his game.

"Hey Star," he said in his most threatening voice from behind her.

Star turned around to see Marco with his arms crossed staring down at her from behind the couch. He was currently giving his best impression of an evil smile as he returned her gaze.

"Marco?" she questioned him. "What are you doing?"

He snickered lightly as he turned his head slightly away from her. "Oh nothing," he said sarcastically. "But tell me, how does this hoodie on me make you feel?"

"Make me... feel?" she repeated.

"Yeah, doesn't it make you feel... afraid?" Marco said mischievously, his plan coming together just as how he had planned it. I can practically feel the sheer terror she must be experiencing! She must think I'm some evil clone or something that kidnapped the real Marco! he thought, applauding himself. Generally, he didn't have a real reason to act like the bad boy he believed he was all the time, so Star was used to his nice, safe (normal) self.

"Well," Star started. "I won't really know until I try it."

Marco was zapped out of his thoughts and blinked in confusion. "What?" Marco said.

Star promptly walked up to him and gripped the hem of the hoodie. "I think I can fit in," she said.

Marco's eyes widened as Star began to lift part of the hoodie up. "Star! What are you doing?!" he panicked, completely losing his confidence.

She didn't hear him as she stepped close enough to him that she was leaning against his chest and slipped her head under his hoodie.

"STAR!" Marco screamed in embarrassment. Heat was starting to rise to his face as he felt Star's head wiggle her way through the hoodie and eventually poking her head out of the same opening Marco's head was poking out of. Her arms snaked their way inside the sleeves of the hoodie to where they were poking out of the same openings that Marco's hands were out of. In short, they were both now inside the same hoodie, Star's head very close to Marco as there wasn't much room for two heads to be poking out of.

"What are you doing?!" Marco said urgently. "Why are you in my hoodie?!"

"You asked me how the hoodie made me felt, but I never wore it before," she shrugged, and since they were both wearing the same hoodie at the same time, consequently made him shrug too.

"That's not what I meant!" Marco yelled. "So uh, could you please move?! You're head is um, t-too close," he stuttered at the end as he realized how close her face was to his.

Star ignored his request and gave him a grin. "You know what Marco? This hoodie makes me feel really warm and comfortable! In fact, I kind of want to," she paused to give a yawn. "-take a nap in this," she said as she began to take steps backwards towards the couch.

"Star, wait! This isn't how it's supposed to go!" Marco screeched as he tried to pull the opposite direction, away from the couch. "You're supposed to be scared of me!"

"Scared?" Star said in confusion.

"Yeah, scared!" Marco said in exasperation. "Doesn't the hood on this hoodie make me look suspicious or even dangerous?"

Star giggled which made Marco blush a deep shade of red. "Dangerous? You look adorable!" she cooed before rubbing her nose affectionately with his. "-Like a giant, lovable teddy bear!"

Marco tried to protest her accusations but found his throat unbearably dry as Star continued to rub her nose on his while pulling both of them towards the couch. His poor brain was melting and the only thing he could think of was how incredibly warm and cozy Star felt leaning against him.

Star eventually dragged both of them towards the couch in a sitting position, which she then proceeded to snuggle closer to him.

"You don't mind if I take a little nap in your hoodie don't you Marco?" she sighed contently as she turned her head to lean against him. "I mean... it's so soft," she said sleepily as her eyes fluttered shut.

"Y-y-yeah s-sure," he said horsely as he tried his best to not think of how nice he felt.

"H-here. I'll just g-get out of my hoodie a-and," he struggled.

"Nah it's fine!" she said, her eyes still closed with a smile on her face. "You feel really comfy too!"

Marco knew if this was to go on, he would eventually comply and be stuck in a very awkward position for a very long time. His nerves were already fried, and he was moments away from having a panic attack.

"Uh, Ihavetodosomethingsuperimportantbye," Marco said quickly before hastily taking off his hoodie, despite Star's protests and running back up the stairs.

Star frowned as she saw Marco leave her alone in his hoodie and run up the stairs.

"Fine, I'll just sleep by myself then!" she pouted, curling into a ball on the couch.

As she did that, there was a small grin on her face as she inhaled the smell of the Marco-scented hoodie before making herself comfortable and finally falling asleep.

*End of Narration*

Ignore how Star reacted. She's just too used to seeing me wear hoodies to realize how much of a bad boy I look! She'll see eventually.

My hoodie? Yeah don't worry about it. I have 10 emergency ones that are already dry cleaned in case something like this would happen. Not that I, dry clean them myself of course. They just, happened to be... like... that.

Uh anyways, let's continue.

Step 2. Always show off your bruises and scars.

Yeah that's right, flout your wounds! The more the better, it shows how tough you are and that you get into a bunch of fights. Just, uh remember to use disinfectant right after. Not that I'm uh, being too safe or anything, obviously. It's not wrong to treat your wounds every once in a while.

Anyways, as a bad boy, you should be picking fights with everyone, these things are just proof you did. Pick fights with all those annoying people you hate, whether it be Ludo and his monsters, Tom after he tries to kill you while screaming "Star is mine!", or even small children that happen to be in your karate class and a higher belt than you because his parents are rich. Man I hate Jeremy.

Me, I get hurt all the time when fighting monsters with Star. Just goes to show you how much of a bad boy I am.

Now watch, Star's going to be pretty impressed when she sees my injuries.

*Narration*

Marco walked up to Star's room with a confident grin. They had just gotten back from a fight with Ludo and he had just found the perfect injury to show her. A scratch on his cheek.

"Hey Star!" Marco called while knocking on the door. "Can I come in?"

"Sure!" a bubbly voice responded from the other side.

Marco opened the door to see Star sitting on her bed, gently cradling a tiny narwhal that must've been summoned by her wand.

"Hey Marco!" she said brightly. "Need something?"

"Yeah," Marco said as he proudly walked up to her and turned his cheek to show her his scratch.

"Check out this scratch I got in the fight today," he smirked, pointing up to his scratch. "Pretty cool huh?"

Star sat there examining his cheek for a few seconds, tilting this way and that to see the scratch. It was fairly hard to see, but Marco thought it was big enough to qualify as a gash on his face.

She's totally impressed by this, he thought as he looked at his best friend trying to spot the wound. She probably thinks I'm the coolest, toughest, most awesome-

Star abruptly interrupted his thoughts with a light hearted laugh. Marco turned to her, confusion written on his face.

"Aww!" she cooed as she reached out her finger to poke his chest. "Does widdle Marco need Star to take care of his owie?"

Marco gasped, appalled by her tone. "No! I-"

"Aww, it's okay Marco! There's no need to be embarrassed," Star said, placing the narwhal somewhere on the bed behind her before taking his hand pulling him down to sit on her bed beside her. "Star is here to fix you right up!"

"Star-"

"Don't move!" Star commanded as she took her wand and summoned a large, pink bandage with hearts and unicorns scattered onto it. To Marco, it looked like the bane of his bad boy reputation. Star took the bandage and happily grinned as she slowly moved it towards the scratch. "Now just let me-"

"Star wait!" Marco exclaimed, desperately grabbing her hands before she could put it on his face. "I-I can't wear that! How am I supposed to be-"

"So, you don't like it?" Star interrupted him, putting on a face of a lost dog as tears started to well up in her eyes and the hearts on her cheeks cracking.

Marco had an internal struggle with himself as he looked at Star's face, which was growing sadder and sadder by the moment, in panic. That bandage was going to lose him his imaginary reputation if he ever got caught. Then again, if he didn't wear the bandage, Star would be balling her eyes out and he would be a horrible friend.

Begrudgingly, Marco sighed in defeat. "...Fine," he relented, taking his hands off hers and turning his cheek to show her the scratch.

Star's face turned as bright as the sun again with happy smile on her face as she took the bandage and placed it right on the scratch.

Marco grumbled as Star was placing the bandage but grinned a little when he saw the happy look on Star's face. He decided it was worth it to just see that smile.

"There!" Star exclaimed as she proudly looked at her work. "Now what do you say Marco?"

Marco groaned half heatedly. "Thanks Star," he mumbled.

The smile on Star's face got wider. "You're welcome Marco!" she exclaimed. "Now come here!" she said holding her warms wide open.

It was progressively getting more and more difficult for Marco as he was trying to make his guide. Star was repelling any attempts he was getting at to being a bad boy with her happy, loving attitude. But maybe, that wasn't such a bad thing.

Marco tried to very hard to keep a smile from gracing his face but Star's smile was too infectious as he felt the corners of his lips turn up. He held his arms wide open to receive the hug. "Thanks Star, I-"

Star didn't let him finish the thought. To Marco's surprise, she didn't give him a massive hug. Instead, she was planning something much different. She took his face in her hands and leaned in to give him a kiss right on where the bandage was.

Marco's eyes bugged out of his eyes as he felt his stomach do jumping jacks. Blood rushed to his face as he tried to calm his heart that had suddenly started beating at a very rapid pace.

Star pulled away and gave him another dazzling smile.

"For good measure," she explained with a grin.

Marco wasted no time as he awkwardly fell off the bed and started heading towards the door. His mind was fuzzy and while he was walking towards the door he was tripping over his own feet and even slammed right into the door head first, much to Star's amusement.

"I-I need to do something," he horsely told her as he opened the door and stumbled outside, making his way towards his room, leaving Star in her room laughing at how brain dead she had made him.

*End of Narration*

IGNORE THAT! YOU DIDN'T SEE ANYTHING! WHAT? NO, I WASN'T HOPING THAT WOULD HAPPEN! SH-SHUT UP! I DON'T LIKE HER LIKE THAT! SHE'S MY BEST FRIEND, I LOVE HER! WAIT NO THATS NOT WHAT I MEANT. WHAT I MEANT TO SAY IS THAT I LOVE HER AS A FRIEND!

Ah, forget you! Let's just hurry up and get on with this stupid guide already.

Step 3. Be a heartbreaker

As a bad boy, girls will definitely be falling head over heels over you because of how cool you are. Just like in all those movies, you got to reject them with no mercy! That's right, you have to build a reputation for yourself as a heart breaker. Take me for instance, one time Janna asked me for an eraser which was an obvious code for "do you like me" (You got to read between the lines) and I straight up said, "I don't have an eraser."

What? That counts right? No? Well, no girl has gone out and actually asked me if I liked them just because their probably to scared to-

*Flashback*

"Hey Marco, do you like me?" Star asked skipping along the sidewalk as she and Marco walked home from school.

"WH-WH-WHAT!" Marco screamed like a girl before running away from her, Star chuckling as she watched Marco's flustered form running all the way home.

*End of flashback*

HEY! Who did that?! You're not supposed to-

*Flashback*

"Marco, have you ever kissed anyone?" Star asked as she walked with him in the school hallways.

Marco fainted a second later and had to be brought to the school nurse.

*End of Flashback*

STOP PUTTING THESE HERE! THIS IS MY GUIDE AND I-

*Flashback*

"Hey Marco, this magazine is asking if my best guy friend would kiss me. Would you?" Star asked him while practicing karate by chopping wooden planks on concrete slabs.

He broke his hand right after.

*End of Flashback*

B-BE QUIET! THAT DOESN'T COUNT! YOU DON'T BELIEVE ME? FINE, WHATEVER! I DON'T NEED YOUR OPINION ANYWAY!

Now back to the point, just sit there and watch me go full on bad boy.

*Narration*

Marco was leaning on a wall outside of the school with his hoodie up, the sparkly bandage that Star gave him still on his face, and hands shoved in his pockets, waiting for some girl to notice him so he could prove that he was really a bad boy.

Funny enough, the first (and only) girl to notice him was Star as she skipped towards her best friend.

"Hiiii Marco!" she sang as she stopped right in front of him. "Watcha doing?"

Marco looked over to see Star's face hovering near him. "Star not now," he said while pulling his hoodie even lower. "I'm trying to get girls to notice me."

Star frowned slightly. "Why?" she asked.

Marco looked up and gave her a frustrated look before taking off his hoodie. "I've been trying to prove that I'm really a bad boy for the past few days, but nothing is working!"

Star's frown turned into a look of confusion. "And that has anything to do with trying to get girls to notice you because...?"

"Because! Bad boys get a lot of girls right?" Marco explained. "So, I'm going to sit here and wait for them to come to prove myself once and for all!" He crossed his arms and continued to lean back against the wall.

Star put a finger to a chin and then pointed to herself. "Well, I'm a girl," she said. "You got me."

Marco shook his head and waved his hand. "No, no, that doesn't count. Your my best friend."

"What does that have to do with anything?" she asked.

"Well first, you only walked up to me because we're best friends right? And secondly, I'm trying to get girls to LIKE me," he huffed.

"Well," she said with a small smile. "I like you."

Marco shook his head again. "No no, I mean like like me."

He continued to lean back against the brick wall and put on his best, bad boy face impression. "Anyways, you can go ahead of me Star," he said eyeing the door to the school. "I'll catch up later."

Star shook her head and stood her ground. "No," she said firmly.

Surprised at the sudden firmness in her voice, Marco looked back to her and raised his eyebrow. "No? Why-"

Suddenly, Star walked swiftly towards him, grabbed his face.

Marco's eyes widened as the hood of his hoodie fell off his face. His face was slowly turning red as he realized what she was going to do.

Star moved forward and crashed her lips onto his, her face morphing to one of happiness.

Marco couldn't believe it. Star... likes me? he thought, standing there dumbstruck, while taking in the kiss. He slowly realized what was happening. Star was kissing him and he was just standing there. STAR LIKES ME! he cheered in his head as he returned the kiss. Yeah, it was going against his bad boy policy but to hell with his reputation if it meant Star was kissing him.

They both pulled away a few seconds later, Marco completely dazed and Star with a wide smile on her face.

"So, are you still going to go through with your crazy plan Mr. Bad Boy?" Star teased.

Marco snapped out of his daze and smiled. "Nah, let's just go home," he said, taking her hand. They both smiled at each other before happily walking back home.

*End of Narration*
