Flavor of the Weak:

She painted her nails a flattering shade of yellow, smudging some on his sofa, which he glowered about, but didn't mention it because she seemed to concentrated on what she was doing, he didn't want to snap her out of it. Because, seriously, he's never seen her get all... girl-ed up for anyone before, except for two times he had gotten to take her on dates. He had been led to believe that those were special occasions. However, this was just a casual day out for the blonde girl situated on his couch. Yep, nothing amazing about it at all. Just a meeting. With a friend. A guy friend. From her college. Where she was known as the party-goer. Yeah. Nothing to worry about there.

Gakupo leaned on his door-frame to his living room, not feeling anxious at all. That was stupid. Why should he feel worried? Rin was allowed to meet with her friends. He wasn't her father. And, besides, it wasn't as if she and the purple-haired man had anything exclusive. Or anything. No, sir. They were just casual... whatevers.

Dammit. What the hell were they?

"Who's this guy, again?" he asked quietly. Alright, it was more of a grumbling than actual words, but he was sure she could understand. After all, she had been pretty much living with him for two weeks now.

As expected, Rin glanced up at him through her bangs. "A friend I made from college."

"You mean, the semester you actually spent there?"

The glance turned into a glare. "Quiet, you," she demanded, waving the brush still held in her fingers at him, "Or this goes in all that 'flaming-gay' on your head you call hair."

His hand immediately went to his scalp. She did not just threaten (and insult) his hair. God damn her, it was manly. In a way. It had to be. "I'm just saying," he appeased. "I don't get why a friend you barely know would drive all the way down here just for a visit. He must be a really nice guy."

"No, actually. He's kind of a sleazebag. In fact, he's more of an asshole than you are," she explained calmly. "And I'll bet any money that he thinks this visit is going to be an extended booty call instead of a reuniting of friends, that's for sure."

The taller man pushed himself off the wall, a muscle under his eye twitching as he moved to sit next to her. She turned back to her nails, trying to paint them neatly with her left hand. "And you're letting him?" The small girl nodded, not looking at him. "That doesn't sound very... well, you. In fact, if it were me visiting you on those assumptions, I probably wouldn't make it out of my car," he dead-panned. Seriously, what was up with this? Rin didn't let anybody treat her like this. She shouldn't. She had more dignity than that.

"Probably," she agreed with another nod. Sighing, she lifted her right hand to her lips to blow on the wet polish there. "But he's just one of those guys, you know? The charming ones you can't get out of your head because..." she trailed off, huffing. "You know," she stated. In fact, he didn't really know, but he had his assumptions. "He's a tool and a user, but I can't let him go."

He gave her a look and she smiled at him wryly, rising from the couch. "Oh, Gakkun!" she exclaimed and a falsetto, southern accent. "That boy just gives me butterflies and makes my heart flutter!" She put one hand to her forehead, being careful of her nails, and turned around so that she could fall back and drape herself across his lap. "Why," she continued in that stupid voice, almost making him grin, "I just can't get him out of my head! Oh, Gakkun, is this what they call love?"

Scowling, he pushed her off of him, earning a giggle and she spread herself out on the sofa to make herself comfortable. "As if," he answered her, although he knew she really wasn't looking for an answer. "It's called being overly-horny. And, honestly, if that's your problem here, I could—"

He was cut off by a cold, thick substance was poured onto his head. It smelt strange, and when he reached up a hand to touch it, his fingers came back yellow. With a belated horror, he realized that Rin hadn't been kidding with her threat earlier.

With a manly sort of shriek, he ran into the bathroom to wash his hair, her tinkling laugh following him the whole time.

–

Two days later, he was at Rin's house, because she hadn't been to his in that time.

Yes, he understood she was probably busy with her... friend, but still! It was the fact that she hadn't even spared him a simple text message in those forty-eight hours and thirty-two minutes that bothered him. Not that he was counting. Or anything.

...He was pathetic. Or maybe he had just gotten so used to her company. That made sense. Obviously he missed her. No matter how much she denied it, she was a close friend of his, among other things. And it wasn't like he had forced her into fidelity, either. Truth be told, they hadn't really talked about that. The closest they came to was when she asked him to define their relationship about a week ago. He couldn't quite explain it, and now he was paying the price, because she apparently took that as a sign to totally ditch him at first opportunity.

Huffing, he slammed his car door, deciding that it was noon and time to go inside. Women, he though sourly as he made his way up the walk.

Gakupo didn't bother knocking. With his luck, Rin was probably still asleep, anyway, so he fished out the keys she'd given him instead. Keys. They'd exchanged keys. If that wasn't a sign of a serious relationship, he didn't know what was. He unlocked her door and made his way inside.

The home was surprisingly clean, considering Rin was kind of a slob without her twin brother around to pick up after her. But, no, everything was neat and tidy, and there was even some clean laundry folded up on the coffee table.

That... was men's clothing. Scowling, Gakupo ignored this and walked up to where Rin's room was.

As expected, when he opened that door, Rin was sound asleep in her large bed, making her seem smaller than usual because of how empty it was. There were random things scattered across the bedroom, including clothes he presumed had not been washed yet and someone suitcase. Her friend's.

A frown gracing his features, he walked to the nearby window and yanked open the curtains, letting the sun in. "Rise and shine, Sleeping Beauty!" he said in an overly happy voice, just to annoy her. When the blonde just grumbled in response, he yanked the bed sheet away from her. To this, she opened one eye, then lifted a hand and promptly flipped him off. "Such a lady," he mumbled under his breath as she turned over on her stomach, seemingly trying to fit herself underneath a pillow.

He was about to reach out and shake her to wake her up more, but she suddenly sat up quickly, eyes darting to the side of the bed she wasn't occupying. She reached out to pat it, then frowned slightly, like she had expected something to be there.

"Looking for something?" he asked before she could stop himself.

She glared at him, then reluctantly asked, "Did you see anyone leave before you came in?" When he shook his head no, her glare deepened, though it was no longer really directed at him. She lifted the pillow on the side of the mattress she was feeling, and there was a piece of paper there.

Rin opened what looked like a note, eyes skimming over quickly, and then she sighed. "What a loser," she stated before yawning and, literally, rolling out of bed. She stretched before picking up the articles of clothing strewn across the room and throwing them into a laundry basket.

He lifted a brow. "You're cleaning?"

"What of it? You think I can't?" The question sounded more like a challenge.

He rose his hands in a apologetic manner. "N-No. It's just that, well, you usually never do it unless forced," he explained.

"Well, maybe if he didn't leave all his shit laying around..." she grumbled under her breath. Finished tidying up, she exited the room, probably to go to the kitchen, but Gakupo didn't follow her, because this afternoon was finally starting to make sense.

Her friend had spent the night, and now he wasn't here.

That was just, well... wrong. And maybe he was being a hypocrite, because he was sure he did it once or twice back when he was in college, but doing it to Rin of all people made it seem worse. You didn't do stuff like that to the blonde girl. She may seem uncaring, but he knew she was fragile. At least on the inside.

Then, he heard Rin start yelling about not having any breakfast and for him to get off his lazy ass and make it for her, since he's the one who woke her up, anyway, and he sighed. Alright. Maybe not that fragile.

"I don't know why he'd do this."

"Just give it up, Rin."

"No. Gakupo, you don't understand. He sent me roses as a way to apologize for standing me up."

"...Don't you hate roses?"

"Exactly."

Night three of this wonderful adventure of hating Rin's college friend, and aforementioned girl was once again sitting on his sofa. She was curled up in a little ball, dressed to kill in stilettos and a cocktail dress. Apparently, her friend and she were supposed to go to this new club downtown. Unfortunately, it seemed that he met someone and wanted to spend the night with them. As a sorry, he sent Rin roses.

Gakupo knew Rin hated roses. She preferred violets or lilacs to any other flower. She believed roses were tacky and overused. Yes, he knew that, by why didn't this apparently amazing friend of hers know that?

Sighing, he leaned back on his couch next to her, and she laid her head on his shoulder. He had still been in his pajamas—Friday night and no where to go—when Rin had knocked on his door, crushing flowers in her hands and demanding chocolate. Unfortunately for her, he didn't have any chocolate, so they had to settle on coffee flavored ice cream, that was sitting in it's carton on his coffee table.

"Don't worry about it too much," he said, trying to comfort her.

"I'm not worrying."

He smiled wryly. Of course she wasn't. "I don't know why you care so much."

"I don't."

Alright, now he was getting annoyed. He shifted and she stopped leaning on him. Turning so that he faced her, he said, "Rin, this guy doesn't know anything about you. You got all dolled up for him, did his laundry, offered to take him out, and he still stood you up. I don't know what you're thinking, but that's a pretty big warning bell. He's only going to want you for a little while, and then he's going to leave and move on and I don't want you being all upset because I told you so. Granted,I haven't met this guy, and I don't know your... history with him, but he's not worth it. Whether he's some old fling or the love of your freakin' life, you could do so much better. You're..." he flushed up to his ears. Jeez, who was he to get all wired up over this? "I mean, um," he said tripping over his words. Sighing and knowing he'd already lost the momentum he was building up, he finished was a pathetic, "Yeah."

Rin frowned up at him for a moment before smirking. "Gakupo—"

"A-And another thing!" he interrupted. "You shouldn't be doing stuff like this anyway!"

Still smirking, she asked innocently, "Stuff like what?"

"Y-You know! ...Hooking up with guys. Or whatever. I told you how I felt about you," the last part was mumbled and barely audible. "I just wish you'd give me a straight answer before doing all this."

He wasn't looking at her now. God, he was lame. Who said stuff like that outside of chick flicks?

"Listen," she said softly. "I don't know what you think went on these last few days, but I was being honest when I told you he was just a friend. I was letting him stay at my house, yeah, but we didn't sleep together or anything like that." Now, it was her turn to blush madly. "I, uh, told him I was... with someone."

Gakupo couldn't help the sappy grin that stretched on his face. "Would that someone be me, by any chance?" he asked hopefully.

"Don't push it." She glared at him, but it really didn't have it's desired effect since she just looked so adorable with her face that shade of pink. Grabbing his ear, she pulled him toward her until she could press a swift kiss on his cheek.

He winced, because her pulling his ear like that did kind of hurt, but appreciated it nonetheless. She liked him. She must, if she rejected that guy. She chose him.

The thought gave him pride. Enough pride to cup her face between his hands and lean down, capturing her lips in his in what he thought was a mind-blowing kiss. She made a little noise of satisfaction, returning it and even wrapping her own arms around him, clutching onto the back of his shirt. When he pulled away, he face was still flushed and her lips were swollen.

"I like you," he stated. "Will you please just verify this relationship by saying that you want to be with me?"

Her lips pursed. "Don't push it," she repeated, slightly out of breath. But then she reached up and kissed him again, and he didn't really care that she didn't quite see things his way.

Her boyfriend.

He don't know.

Anything about her.

He's too stoned; Nintendo.

I wish that I could make her see,

she's just the flavor of the week.

She makes me weak.

A/N: I enjoy jealous Gakkun way too much. As for Rin's college friend? That can be up to your imagination. I don't really have anyone in mind, but I'd love to hear what you guys can come up with. Oh. Someone should write a back-story for them. That'd be epic. Like, seriously. I'm too lazy, but yeah.

Anyway, R&R
