Prologue

"Happy Birthday, Takuya!"

"Chocolate! My favourite!" Takuya Kanbara, a young brunet boy who had just turned ten, exclaimed when he saw the chocolate cake with candles on them, waiting for him to blow them out.

"Make a wish, Takuya!"

"Blow them away, Taki!"

"HEY!" Takuya shouted half-heartily at one of his friends for the nickname, before looking at the cake. Then turn to his mum. "Thanks mum!"

Smiling, Yuriko watched as her son's friends sing the birthday song, and then said. "Takuya, blow them out."

Taking a deep breath, Takuya blow them all out, while his friends cheered.

"Alright, cake!"

"I have a slice after Takuya!"

"No, I'll be the one after him, Yasuo!"

"Hey, cut it out, guys!" Takuya said, hoping to stop his friends from fighting.

Yuriko smiled, and then frowned. Studying her son, she saw a thin layer of dark energy. Her eyes widen. 'No, the Shadow Heart comes early!'

"What's wrong, honey?" Takeshi asked, looking at his spouse with concern.

"It comes early, Takeshi!" Yuriko whispered to her husband, panic in her voice was clearly heard by her husband.

His own eyes widen, Takeshi glanced at his son who's cutting the cake and giving slices to his friends. "I guess we better tell him a lot earlier then planned."

Still looking worried, Yuriko watched as the aura around Takuya slowly grows bigger, only seen by family members.

As they joked around, the brunet boy slowly found himself unable to laugh at his friends' joke and forced himself to make one. Heck, Takuya even have to force a smile. 'What's happening to me?'

After the party...

After his friends went home, Yuriko went into Takuya's room after tucking in Shinya. Sitting on Takuya's chair, she said softly. "Takuya?"

Sitting up in his bed, Takuya turned to his mother, looking at her with his eyes, which is slowly begin to darken. "Mum?"

"Takuya, have you been feeling that you can't feel emotions?" Yuriko asked. "Even if you can't laugh?"

Looking at his hands on his lap, the brunet boy asked. "Mum, what's happening to me?"

"It's a curse." Yuriko replied, the answer made Takuya looked up.

"A curse?"

Taking a deep breath, the brunette mother began to explain. "Centuries ago, our ancestor in Ancient China had angered a spirit. The spirit put a curse on him as revenge, the curse that affects the heart."

"You mean I'm going to have cancer?!"

"No!" Yuriko whacked her son's head, lightly. "I mean emotionally! If that's true then you won't be here!"

"Oh..."

With a sighed, Yuriko continued. "The curse was Shadow Heart, a curse that makes the host unable to feel emotions. However, it can only be broken by a special person outside the host's family who can make the host feel even the slightest emotion."

Takuya looked down at his lap where his hands are rested, as his eyes darken more, the brunet boy himself feels very hard to feel emotions.

"The curse went on for generations, until four generations ago, your great-great grandmother's Shadow Heart was broken by a Japanese boy." Yuriko continued. "Their child's Shadow Heart was weaken and appears later. They figured out that with less Chinese blood in our veins, the Shadow Heart weakens."

Takuya's eyes finally became dull and emotionless as he listened to his mother. When he looked up, Yuriko's heart almost breaks at the site of the dull eyes.

"Since then," Yuriko managed to let out. "The Shadow Heart appears when the host is thirteen or older."

"Mum, what about me?" Takuya asked, rather emotionlessly. "I'm ten."

"I'm not sure, Takuya. There were maybe some problems in your genes to make it appear earlier, who know?" Yuriko whispered, tucking her eldest son in his bed. Before the Shadow Heart takes affect, Takuya always complained about being too old for any 'special family obligations', but now, the mother missed it.

"Good night, Takuya." Yuriko whispered, turning off the lights.

"'Night, mum," The brunet boy let sleep claimed him for the night, closing his eyes.

Yuriko closed Takuya's bedroom door quietly, thinking to herself. 'Whoever Takuya's special person is; I hope that person can break his Shadow Heart. It's so early!'

With that, Yuriko went to her bedroom she shared with Takeshi, ready to turn in for the night.
