Full Summary:

Yumi's been chasing after Light Yagami since they were kids. But he's never even given her the time of day. Now when they're going to the same college and Yumi manages to score a date with the hottie, the date ends in heart break for Yumi. So she decides to turn the tables and break Light's heart instead.

Prologue:

Just Another Girl

"Um, I was wondering Yagami-san, if you would like to go on a date with me?" I bowed, to hide my blushing face.

My name? Yumi Asihara. Freshman in Tokyo University, Japan, also known as To-Oh.

Age? Eighteen years old.

Right now, I seriously feel like I've just committed social suicide. A girl asking her crush, the most popular, smartest, and cutest guy at To-Oh out for a date when he probably doesn't even know her name?

Yeah, I'm really trying to kill myself.

I looked up to see Mikami, a black haired junior, whisper something to Light as Light smirked, and I suddenly felt very self-conscious.

"Sure…" Light trailed off. I forgot I didn't give him my name.

"Oh! I'm Asihara Yumi, Yagami-san," I gave a quick bow, not being able to meet Light's golden brown eyes.

"Please, call me Light," Light smiled nicely. "I'll pick you up at around seven okay?" he said as he, Matsuda and Mikami all walked away together down the walkway.

When they were out of earshot, I squealed for joy and ran off to my dorm room to get ready for my date with Light.

-The Day After-

"I had a great time Light," I told the brunette as I trailed after him as we walked down the same walkway as yesterday.

"Hmm…yeah…right…" Light said as we walked past a couple of girls that gave Light flirty eyes.

Last night had been amazing. We went to a small club where a local band was playing. We got a couple of drinks and sooner or later, I found myself waking up in a hotel bed, half naked under the sheets. It would have been the best night of my life.

"I was wondering what we were going to do for our second date?" I asked, a blush coming to my cheeks.

Light gave a small sigh before turning around and looking at me. "Listen, Yuki-"

"It's Yumi."

"Yumi. Yeah about that date last night? It was a one-time thing. You understand right? We're not really going out again. I just did that to be polite. I'm sorry," Light gave a small nod before walking away, towards the group of girls that just past us.

I didn't know what to say.

My vision went cloudy as I ran as fast as my legs could take me back to my dorm room.

-o-o-o-o-o-

Unknown to either one of them, a raven haired genius, sat in a crouch on the bench had been watching and listening to the whole problem.

"Interesting," he muttered to himself as he looked at Light's retreating figure then observed the brunette girl, who stood silently before running towards the dorms.

It was then he got up and walked towards Light.

"Light-kun," he waved to the light brown brunette boy as he waved at the group of girls he had been chatting with.

"Hello. Do I know you?"

"Yes. I was the other freshman representative that joined you in giving a speech. I am Ryuzaki," he introduced to the other boy. "I wish to talk to you about something," he said as he sat down on adjacent bench as Light joined him on the bench.

"What do you wish to discuss?"

"Well, I observed that little disagreement you had with Ms. Asihara just now, and I would like to make a bet with you…"

-o-o-o-o-o-o-

He's an ass! How could I have spent my whole childhood chasing after him?

Because you know deep down, he's your prince charming and forever will be.

How can you say that conscious?

I sighed and thought back long ago to twelve years ago. From the first day I met him at primary school, I just knew he was for me. We were friends, but that was long ago. Before being pretty meant you were instantly popular or being a player didn't mean that you toyed with girls' hearts.

I finally got to my dorm building and rushed up the stairs two at a time, accidentally bumping into someone.

"Oh! I'm sorry-. Hi Yumi! What's up? Wait, why are you crying?" the familiar red head asked me, putting a reassuring hand on my shoulder as he put down a basket of laundry on the floor.

"Oh h-hi Matt!" I struggled to speak between my tears, giving him a fake smile. "I-I-I'm just peachy! Why? How are you and Mello doing?" I lied, changing the subject.

"Yumi, don't change the subject to me and my Mels. Answer the question. What happened?" Matt asked gently as he picked back up the laundry basket and helped walk me back to my room.

"I-It's just- just- how could he be so mean?" I asked, more to myself than to Matt as I threw myself onto the bed, burying my face into the pillow.

"Who?" Matt asked, carefully rubbing my back, voice full of concern.

I've been with Matt since high school. We met since our cruel teacher decided to break up the class into social hierarches with Light and the rest of the cool group at the top, the regular students in the middle, and the social rejects and the misfits at the bottom, which meant Matt, Mello, and me.

We started talking then soon we started hanging out. Matt was so sweet and Mello was the opposite. Occasionally I would call them Sweet n' Sour, before Mello would storm off pissed and Matt and I would have to chase him down to tell him I meant no actual harm. I actually started falling for Matt before he told me he was gay and that he liked Mello.

Secretly, I set them up so they could have 'alone' time and before long, they started dating. I sometimes felt a little like a third wheel when we would go out together, but I was purely happy for them and their relationship.

"Light."

"Is this about your date last night? I thought you said you had a great time. What happened this afternoon?"

As I told Matt the whole story, I noticed his expressions changed drastically almost every minute. From sad, to anger, to curiosity, to creepy smile.

"You know what this means?" Matt asked, that Cheshire cat smile still intact on his boyish face.

"What?" I asked, lifting my head to stare at Matt with bloodshot eyes.

"Revenge."

"How? B-but that's not me," I stuttered, thinking of what type of revenge plot that Matt was thinking of.

"Suck it up Yumi. That jerk face broke your heart! What he deserves is revenge," Matt firmly stated as he got up and opened my closet.

"But I can't do that. It's mean, and it's not me, and it's- what are you doing?" I asked, watching as Matt threw shirts here and there onto my carpeted floor.

"Light's been breaking hearts for too long and needs to be brought to justice," Matt turned around, all joking sense from his face gone.

My face hardened in realization. It had been a while ago, but I remembered why Matt was serious about Light and his player ways. Light had been multiple of Matt's firsts. First love confession to. First to lose his virginity to. First heartbreak. All in a couple of weeks. I've never seen Matt so destroyed in the time I've known him. It took months to get over Light, but I could tell that Matt was never fully over it.

I needed to do this for myself. For Matt. For all of the guys and girls that have confessed to Light, strung along, then had their hearts torn out.

"What do I need to do to get revenge on that bastard?" I asked through clenched teeth, fire of determination of in my bright green eyes as Matt filled me in on the details of his plan.

-o-o-o-o-o-

"What do I get if I win?"

"Whatever you wish. Money is no object," the pale young man replied.

"I'll have to get back to you on that. What I fail?" Light asked, knowing that failing was never an option. His ego would never allow him to fail a bet to someone who looked like they've literally been living under a rock for years.

"You will have to stop your player ways," Ryuzaki stated simply.

"Deal," Light nodded as he extended his hand towards Ryuzaki who just stared blankly at it. "Be prepared to lose Ryuzaki-san," Light gloated.

"Oh, I don't think that would happen Light-kun. For you see, I always win," Ryuzaki shook Light's hand as they both sealed the bet.

Yumi Asihara, you will be mine. One way or another.

-o-o-o-o-o-o-o-

"Are you sure?" Matt asked as we walked out of the salon, bags of clothes in hand.

I flipped my newly dyed red hair over my shoulder before giving Matt a cheeky grin.

"Never felt better," I winked, getting the attention of some guys around us.

Light Yagami, I will steal your heart and crush it you cold bastard. One way or another.

-o-o-o-o-o-o-o-o-o-

Oooohhh! My! Isn't this exciting?
