Author's Note: First time writing anything for this series. I get a little confused at which name to call them, their first or last, so I just call them by what I hear them call one another the most. Also we're going to pretend that pre-despair, their principal was really lenient with the students because he figured they were responsible and intelligent despite their young ages. And they live within the academy so they can do what they want! Yes, we will just go with that. Enjoy. Oh, and hopefully it doesn't get confusing with the switching back and forth from present to past. All comments and reviews are appreciated!

Title: Mistake

Rating: Teen for teenage drinking and some mature situations.

There he was, crying again. Just like he always did when any little thing went wrong. Except this wasn't just any little thing. This was huge. This was an accident. No one was supposed to know. Sitting up in bed, Chihiro furiously brushed his messy bangs out of his face as he stared with blurred vision at the man before him. His head spun from the speed at which he rose as he had to press a shaking had against his stomach in attempts to not throw up again. "I-I-I'm sorry…"

"You're sorry…?! You… you lied to me!"

"I didn't lie…" the smaller boy stammered from atop his messy bed, his entire body shaking from head to toe. He was sweating profusely, both from embarrassment and alcohol intake. The power in the other man's voice was enough to raise Chihiro's temperature and more tears welled in his pale hazel eyes. "Stop crying," he thought to himself, but it never worked. Just thinking of how scared he was sent him over. He dropped his blushing face into his palm, sobbing loudly. "I just…"

With a large huff, the man before him shook his fist in Chihiro's direction. "You knew where this was going and you didn't say a fuckin' thing!" The words shook the smaller of the two down to the bones and all he could do was cry. Cry and suppress the urge not to get sick again. "You lied!"

"I didn't ask you to kiss me!" the blonde shouted through thick sobs, this time using both hands to cover his face, which tingled with anger and disappointment. He wasn't the kind to get angry, but he couldn't help it. He was angry at himself, at the situation. How could he be so stupid? "Mondo, please, just…"

"No!" Mondo bellowed and for a moment, Chihiro was thankful that the walls were sound proof, because that simple shout was enough to shake the walls. The slam of the door following after almost knocked a picture lose from his nearby dresser. He stared at the closed door through soaked vision, his cheeks flushed with bright red anger. His tears felt hot with desperation as he finally threw himself from the bed, racing to the door. Instead of flinging it open, however, he locked it tight to avoid anyone else making their way in. Even Mondo, although he was sure the man was never coming back.

The sudden jolt to his feet reminded him about how unsteady he had been and his body spun fast like the fan hanging from the wall. He was going to be sick for at least the fourth time tonight. He turned on his heel, nearly tripping over his coat, which was lying on the floor, and made haste towards the bathroom. The light was still on from earlier and he dropped to his knees before the toilet, purging whatever was left in his stomach inside.

After a moment of being on the floor, he had finally gotten enough out of his system that he was able to stand. He grabbed the bathroom counter and pulled himself to his shaking feet, blindly searching for his tooth brush which was been idly thrown aside earlier. He stared at himself in the mirror, seeing a stupid, trembling little girl that he had lead everyone to believe was true. No one knew he was a boy… well, now someone did.

Today was Kiyotaka Ishimaru's birthday, and the headmaster had always given them permission to celebrate their birthdays basically however they chose to as long as they didn't leave the academy. Many of them didn't leave the academy often as they traveled far just to get there, which in turn meant missing out on celebrating important occasions with their families. So their treat was spending their birthday however they chose, which usually lead to a night of heavy underage drinking which resulted in silly mistakes such as falling down the stairs or jumping into the pool with all their clothes on. Nothing ever too dangerous and so far no one had done anything really stupid.

Until now. Chihiro whipped on the faucet, sliding his toothbrush beneath the stream of water as he groggily searched for the toothpaste. Not everyone always drank when they got the chance. Togami indulged himself in maybe a glass of wine, but would never be so brainless as to let his calm, dominant behavior slip before the others. Sakura always chose to opt out, instead becoming the chaperone for the others should things turn sour, such as Asahina throwing herself and Hagakure into the pool fully clothed. Kirigiri didn't like the taste of alcohol, and Fukawa was too much of a bumbling mess to want to touch it. Others sipped casually, and some took it as a challenge. Particularly Mondo and Ishimaru. They took everything as a challenge, and initially it had started as a competition just to see who was the better man, but eventually they solved their bull headed, dominant issues, and now everything was just "friendly" competition.

Staring at himself in the mirror as he brushed the remnants of lemonade flavored booze from his teeth, he noticed the mascara running from his eyes which were red with disappointment. The girls had done him up before the party, as they always did. He didn't care much for makeup, despite using women's clothing as a cover up for his weakness. It always seemed like an unnecessary hassle for sitting around in a classroom or hanging around people you see on a daily basis, but for a chance to fit in with the girls and further bury his secret, he did most of what they asked. But now he just looked like a mess. He didn't look cute. He didn't look pretty. He looked disgusting. Felt it, too.

Chihiro was usually one of the ones who didn't drink. He felt obligated to watch over the others if they got too sick, or if anyone spilled anything on the nice floors, or accidentally kicked over a chair in their drunken stupor. Plus, he had never had anything more than champagne from his father once when he was young as they celebrated the New Year. It tasted awful, and even just a sip was enough to make him want to vomit, so he never tried again, even though given the opportunity multiple times over the year or so at the academy. But tonight felt different. For whatever reason, he felt as though he needed to be one of the guys, despite that everyone thought he was a girl.

So instead of sitting in the background, grabbing drinks for anyone who asked, or walking any of the girls to the bathroom if they started to feel light headed from one too many wine coolers, he grabbed a cup of something Junko whipped up (said she had snuck a taste of it at some modeling party and then learned the recipe), and sat amongst the ones making a game out of their drinking. At first he did nothing more than that. Just sat wedged between Mondo and Ishimaru, taking light sips of his lemonade concoction, watching them flip cards and give out drinks to the other players. He didn't catch the rules, and the more he sipped quietly, he found that it really didn't matter. Seemed like someone was always drinking regardless of what card they flipped or what the rules stated.

"I'm tired of this game…" Hagakure grunted as he looked towards the bottom of his cup, which was quickly be drained numerous times throughout the game. For a Super High School Level Shaman, he was pretty poor at determining the numbers on the opposite side of his cards. "Let's play something else, dudes…"

The other boys-Leon, Naegi, Ishimaru, and Mondo- began calling out ideas for different things to play, until eventually the conversation dissolved and they all began idle chit chat between themselves. They didn't speak to Chihiro much because it was odd that one of the "girls" was sitting with them to begin with. Generally the other girls would take this time to drunkenly explore the academy, lounge around in the rec room, or take selfies in whatever reflective surface they could find. Chihiro usually tagged along to hold whoever's hair if they got sick. "Yo, you alright?" Mondo suddenly piped up, unusually quiet for moments like this. "How much you had? You're red."

"Oh… um…" Chihiro mumbled as he stared down into the bottom of his cup, which was nearly empty. By the boy's standards, not nearly enough to make a dent, but for his tiny body, he was feeling it hard. He narrowed his eyes and then showed the contents of his cup to the biker. "That much…" The smaller of the two could feel his cheeks burning, and somewhere in the back of his mind he was embarrassed for drinking the entire cup that fast. But it tasted so good, just like lemonade, that he hadn't even noticed his speed.

"Be careful. Junko makes that stuff strong," the biker grunted, returning his attention to the guy's conversation, which had somehow been averted to the chickens upstairs in the gardens. Chihiro nodded slowly, attempting to concentrate his attention on the conversation, but Hagakure was going on one of his spiritual rants about the way the chickens looked at him when he went in there, and it was extremely hard to follow. Sober, his rants were hard to follow. It was a lost cause in this state.

The blonde sighed and absently leaned his head against the biker's shoulder, shutting his eyes for a moment. His eyelids were so heavy, why wasn't everyone else sleepy? "Yo…" Mondo murmured again, this time shaking his shoulder causing the programmer to flutter open his eyes. "You're… really red. You allergic or something? Never seen you drink."

"Uhhh… I'm… o…kay, I promise," the smaller one grinned with heavy eyes, refusing to lift his head from the biker's shoulder. Thanks to his inebriated state, Chihiro hadn't noticed how awkward he was being. "Can I have a little more, I think… I ran out, please."

Standing in his bathroom, he spit out the foam and rinsed his toothbrush under the faucet. There was his first mistake. No, first mistake was drinking in the first place. Asking for more was his second mistake. And a second cup quickly turned into a third, and after that, he couldn't even remember everything he had taken in for the night, but it was definitely too much. He rinsed out his mouth with a nearby cup and then shut the faucet off. His throat burned from the vomiting. He hoped nothing else snuck up on him because he was tired of getting sick. It was like his body was punishing him for even drinking in the first place.

Sniffling loudly, he lifted his head to stare back at his reflection. He used the back of his hand to wipe the mascara from beneath his eyes, the black smearing against his skin. His cheeks began to dim, but his eyes still stung with tears. He may have resolved the problem of his upset stomach, but the headache and the fact that Mondo knew his dirty little secret weighed heavy in his body. How was he even going to walk the hallways again? Would the biker tell everyone? He was surely upset… not only did Chihiro "lie" to Mondo about his gender, but he drunkenly led him on. Mondo was angry… but would he be angry enough to tell everyone he kissed another boy?

Author's Note: That's all for now as I need to study for a final and get some artwork done. Plus I want to gauge some reactions. The next few chapters will probably just be Chihiro trying to remember what lead up to the end of his night, and then after that I'll get into resolving the problem, if it will be resolved. Hopefully next chapter is longer. Reviews and comments are again, appreciated! Hope you liked
