It's All Fun and Games Till You Fall in Love

Chapter 1: The Wager

School was school, what more could Rin say? He always claimed to be a in-field type of guy instead of being in a classroom, but he knew that with his goal of becoming an exorcist there was going to be some boring parts as well. As soon as the bell chimed, he was the first one up, ignoring Shiemi's exclamation of "I thought you were asleep, Rin!" and heading out of the classroom, slinging his sword on his back.

He felt someone close behind him, and glanced back not surprised to see Yukio, strutting to his side. "Rin, I was meaning to ask you, yesterday when Mephisto took you out of class, what was that all about?"

Rin questioned the same thing, and rolled his shoulders, indicating that he didn't have a clue. "Told me he had something to show me, then eventually took me back after asking me some really weird questions, saying that his sister wouldn't actually have interest in me, or something or the other," he stated, leaving out the questions to avoid any questioning that his brother might make him endure.

"I see... so, nothing regarding the fact that you are the son of Satan, and what not?" he asked, raising a brow.

"Nope."

Rin did find it odd now, at the mention of their birth father. Whenever Mephisto was around, or even talked to him, it was generally revolved around said topic. Not once was he really mentioned, which confused him quite a bit. Yukio seemed to have the same thoughts, his brows furrowed as he pondered what the principal was up to. He broke out into a smile, when he noticed his brother observing him curiously and started forward once more.

Rin was about to ask, but turned around at the sound of his name being called.

"Rin! Yuki-chan!"

Shiemi ran down the hall from their classroom in an attempt to catch up with them. Not even a few feet away, she tripped flying forward into Rin, who caught her as best as he could. "You alright Shiemi?" he asked, smiling at her clumsiness.

"Y-yes, thank you Rin!" she smiled up at him, regaining her balance, "I was wondering if you two had picked who you were going with to the dance in two weeks?"

Rin blinked, "What dance?"

"It's still two weeks away, and as a teacher I figured I would just go and supervise," Yukio stated, rubbing the back of his head.

"You knew about this too?" Rin accused, pointing to his brother, then letting his hand drop as he sighed, "Why am I always out of the loop?"

Shiemi giggled and smiled, "Yuki-chan, you're still a first year, so you should still have a date," she said holding her hands in front of her almost nervously.

Rin smirked, and took this as his lifeline, "Yeah, Yukio! You should take Shiemi!"

Yukio paled and looked between the two and sighed seeing Shiemi's eyes light up, "Alright, Shiemi, would you go with me?"

"Of course!" as soon as she turned away, Yukio glared at his brother, earning an innocent whistle in return as he headed down the hall.

"You know, she was probably aiming for you to ask her, brother..."

Rin smirked and chuckled, swinging his hands behind his back, "But your the one who is taking her," he said, turning and opening the door to the entrance of the cram school, and leaving his brother who had his hand on his chin, thinking.

If only Yukio knew the truth, then possibly he'd leave him alone on this matter. He was always hinting that Shiemi had a crush on him, and though the thought didn't exactly disgust him, he didn't really like the idea, either. His thoughts turned to Mephisto. What was he up to? And why exactly did he feel the need to try and introduce his sister to him? It was all a little weird. He let out a wide yawn, looking at the clock on his phone and heading to the dorm in hopes to get some food and then some sleep.

Rin shot out of bed, grabbing his phone and groaning at the time almost instantly. Kuro hopped up on his lap and looked up at him, tilting his head to the side, curiously. "What's the matter, Rin?"

Rin shook his head and let out a soft sigh, running his hand through his hair, "Bad dream..." he scooted out of bed, getting into his school uniform, ignoring the fact that it was only three in the morning and his brother was sound asleep in the other bed. He made up his own bed, all while Kuro was staring up at him with wide eyes, and headed out the door, Kuro following close behind him.

"Feel like playing, Kuro?"

The cat demon thought for a moment then shook his head looking to the ground thoughtfully, "What was the dream about?"

Rin stopped for a second, thinking as he turned towards the sinks, turning on the faucet and splashing water on his face. He lingered over the sink, trying to recall the dream, "Not sure... All I can remember is that damn clown's stupid grin-"

"I sure wish you would come up with a better nick name for me than that..."

Rin blinked and jumped back, nearly stepping on Kuro on the process as Mephisto floated down from the ceiling, tilting his head to the side, his famous grin plastered on his lips, "Spying on me now, you old creep?"

The older man's smile widened further as he hopped down, standing next to him looking down at the sink, "Better brush your teeth, wouldn't want your pearly whites to get yellow, now would we?"

Rin's eyes narrowed as he scowled and did what the other suggested, staring at him from the corner of his eye. Spitting out the toothpaste and saliva, he looked over to the man, who was glancing at his hands absentmindedly. "Can I help you with something?"

The man looked up at him and smiled, shaking his head, "Just wondering why the son of Satan feels the need to be up and about at three in the morning," he stated, walking around him, peering at him from the other side, "Up to something?"

Rin rolled his eyes and took a handful of water, slurping it, sloshing it around in his mouth, then spit it out in the sink, taking a towel and wiping his mouth clean, tossing it against the sink and heading towards the stairs.

"Not going to wash your face?" the man cooed, earning a glare from the younger male.

"Not with you staring at me, you fucking creep." The principal laughed, throwing his head back, smiling as he calmed his laughter down almost immediately as he followed him down the flight of stairs. "And now your following me... What the hell do you want?" he asked, from over his shoulder, not even bothering to look back at him.

"I want to make a wager with you."

Rin blinked and stopped walking, slowly turning to meet his gaze. "Wager?"

"I can make you love me in two months time. If I win, I get to keep you. If you win, I will see to have you promoted up two ranks of Exorcist," he stated, emphasizing the two ranks by sticking up his index and middle finger on his right hand.

"What do you mean... by keep me?" Rin asked, taking a step back, looking confused.

"So, you're worried about falling in love with me? Hm, are you making this your confession-"

"What are the rules?" Rin growled, baring his teeth, his tail flicking back and forth agitated.

"I can do anything I deem fit to try and make you love me. You can try to escape my maneuvers, but you cannot say no to them once I have you. You cannot use your powers to avoid me, and no lying about your feelings just to win," Mephisto stated, his grin widening as he saw Rin's face contort to an expression that indicated he was thinking.

"Alright... You're on," he stated, holding out his hand, which the older man gladly shook chuckling as he removed his hat and bowed.

"Pleasure making a wager with you. I'll give you a forty minute head start."

"Forty minute head start?" Rin asked, his eyes widening slightly as he now wondered what he was getting himself into.

"You don't think I'd waste precious time in not trying my hardest to win? I suggest you do the same," he said, twirling his umbrella almost obnoxiously.

Rin looked down at Kuro who was looking between the two curiously, then gulped looking up at the man's almost evil grin. He turned, and sprinted down the stairs, ignoring Kuro's yells for him to wait up for him, and sprinted out of the dorm building at top speed. He felt a sort of weight on his shoulder, only looking at Kuro for a second, who was now clinging to his jacket as he ran. "What is that man up to, Rin?" he asked, struggling to stay on his shoulder.

"I don't know, Kuro. But I'm not waiting around to find out."

At this point, he didn't know where to hide first. What was an obvious spot to the older man, and what wasn't? At first, his thoughts wandered to the amusement park. Would that be a good place to hide until class started? He frowned. The man could catch him on his way out of class, he forgot that minor detail. He hid behind a building and looked to Kuro, his eyes betraying his confident expression to show worry. "Do you think he could catch me in class? After all... He isn't a student, he can wander around as he pleases..."

Kuro shook his head to answer that he didn't know, making Rin let out an exasperated sigh, "I should have thought this whole thing over first... This sounds like it's going to be a pain..."
