Prologue

The beginning.
It's never a simple step.

Only two boys were left in the classroom to lock it.

One sighed while he approached the other.

The one that all he wanted to be was Edogawa Conan. And to the extreme point of unfortunate, he was the closest to his love interest. However, he thought it was appropriate to ask.

"Check this out! Conan-kun!"

Pulling on his arm gently, Mitsuhiko barely managed to tear Conan's eyes off of one of Mitsuhiko's mystery books. Unwillingly, Conan looked at him.

"What is it?"

Then, Conan stiffened at the sight of a cooking magazine which held the photo of a chocolate cake. With strawberries laid upon it in a shape of a heart.

"You mean this cake?"

"Of course!"

"You're planning to make this, aren't you?"

Mitsuhiko winced at his fast deduction. He realized that Conan probably knew the future receiver of the cake and his cheeks reddened. "Yes."

Suddenly, Conan's phone rang. It was Ayumi.

"Hold on a sec, Mitsuhiko. Phone call." He mumbled to Mitsuhiko.

"Hey, Ayumi. What's up?"

A charming but somewhat nervous voice answered. "Conan-kun...Can I ask you a favor?"

"Sure. What is it?" His curiousity increased.

"Could you come to the class tomorrow from the other side of the school?"

"Um. Okay. That's...gonna take a little bit more time. But why?"

"You'll see." She chuckled. "See you tomorrow!"

"Oi, Mitsuhiko." Conan shut his phone. "Do you know what's at the other side of our class?"

"Eh? You mean around Class G to K?"

"Yea."

"Hmm. There's nothing special...Wait!" Conan tensed. "Since Christmas is approaching..." Oh no. Conan thought as Mitsuhiko gave him the sentence. "I think the school is planning to place mistletoes. Why?"

"No, it's nothing. Go on."

Mitsuhiko paused over Conan's horrified face. But then, he continued gleefully, pointing at the magazine. "Anyway, isn't this great? Anybody will love it! Maybe even-"

"-Haibara-san. You mean." Conan gritted his teeth, finished the sentence and turned his eyes back to the novel. However, Mitsuhiko still droned on, still in his dreams.

"Yes! Isn't that awesome? Someday, I'll make a really large- no, she'll probably like smaller ones- so I'll make a cute chocolate cake with small strawberries in the shape of a heart! I'll even try to wear a suit, and invite her to my house!"

At this, Conan made a strange noise. Thankfully, Mitsuhiko was too deep in his dream to notice.

Man. These kids are seriously going too far. Seriously! Now Ayumi is planning to-to kiss me or something tomorrow. Shaking his head slightly, he imagined the face of a reddish-brown haired girl, her beautiful face a little pinched at the sight of Mitsuhiko's dream. He'd better get back to liking Ayumi instead of that evil-eyed girl if he doesn't want to get a life-permanent shock-

"Actually, I'll do that this Valentine's Day. And then, I'll have candles lit on the tables around the cake, and-and maybe a confession and a ring-"

"No."

Cut in the middle of his sentence, Mitsuhiko turned his head. "What? Why?"

"Because she's taken."

"By who?" His eyes enlarged with fear.

"By m-me."

WHAT?!

Even as he uttered the last words, his eyes expanded and he almost covered his open mouth. he couldn't believe he said 'me' instead of any name he could think of. What the hell did I just say?!

-End of Prologue-

A/N: So the idea is pretty classic, and a bit OOC, too. Since Conan would have a sharper mind than to say Ai is taken by him. Reviews are welcome :)
