"Okasan, what flower is it? " a cute little girl running happily under the sakura tree. It was April, the season for sakura and theat was her favourite season. Everything was pink and that was cute. The girl continuesly jumping under the sakura tree, playing around as if she lived in her own world. A middle-aged woman watched her carefully with a smile, sometimes she laughed. Looking at her only daughter and child really make her sorrow away. She was really happy and hoping that the season will always continue as it was. 

"Jiyeon~ it was sa-ku-ra. Cute isn't it? Like you.." 7-years old Jiyeon laughed happily. Okasan is the best! She ran happily towards her okasan, hugging her tightly. somehow, a sakura'flower fall on her shoulder. Jiyeon took it and hand it to okasa. 

"Okasan, this is for you. I love you" She kissed her on the cheek, Okasan smiled. "Thank you, pretty" 

That was the last time. The last time she could see Okasan smiled when suddenly a black car approach and two men came out from the car. Jiyeon silenced, she did not afraid. She used to them. Okasan said, they were their guards. A special guard, protecting them anyway, which make her felt special as no other people had a guard like that. 

"What are you guys doing here?" 

"Nee-chan, actually..." Okasan's face looked depressed. No, not only her, the other guard too. Jiyeon really cannot understand it. The situation become more serious. Okasan pull her hand and hurriedly went into the car. She realized tears flowing from Okasan's eyes but she did not know why? Okasan...the sakura flower fell, being stepped by one of the guard. 

When they came to their house, it not a house anymore. Everything turned black. Burned down. There are likely 10 fire fighters in their house, everyone looked tired, as they trying to fight with the fire but it looks liked  they were lost. Their house...was 100% burned down. When Okasan see two fire fighter carrying what appear to be a corpse covered with the plastic bag, she cried hysteriacally. Jiyeon really looked confused. Why Okasan cried over that 'thing'? She just standing there like a mannequin, no response. Jiyeon was completely lost in her own world. She not even cried. Suddenly a pair of hand backhugging her. She's surprised. It Oyabun, her grandfather. Oyabun, who he want her to call him, is a leader of a big guard groups as what she believe. 

"Jiyeon-san, fight for your father,...." He whispered. 

That fateful day, she lose her home, she lose her father and what is the most hurtful for her, she lost Okasan's smile. 30 days without her smile for even once before she decided to not smile forever. Okasan, she jumped from a building and leave her behind a sakura flower, and she witnessed it. The terrible sound come from the cracking sound of bones and skull, the red thck liquid flow from Okasan's head, Jiyeon still remember that. It was in April 1998 which finally become the birth of the new Jiyeon, a cold-blooded, trained Yakuza's heir. She hated everything, sakura, okasan and the damn killer who destroying her life. 

8.30 am. SHOWA APARTMENT

'Ring!!!!!" A noisy alarm clock put an end of her dream. Jiyeon woke up suddenly. The dream is coming again, the memory that she really want to throw away but sadly it can't. She stopped the alarm and sit in the end of the bed. Without realized, the tears flow slowly, and finally turn to cry. She did not know why but she really at her bottom on that morning. "Damn.." She cursed slowly, her voices cracked, her eyes sore. 

A laptop beside her bed is still on, the email is still there. The email from oyabun that send to her last night. The trip mission. 

"Taking part a trip is a must. Your progression is so slow, Jiyeon-san. How come i can expecting more than this? That Murakama's heir should be there. I'm sure he or she is a part of your class, 3A. I'm waiting for the good news- Oyabun"

Jiyeon looked out the window. The sorrowful morning as sorrow as her heart. Murakama's heir? Is he or she was really that important?. Oyabun did not even asked about the other name in this list other that damn betrayer. She really suspecting something. Is this mission is just a shadow for capturing the heir? Sometimes, Jiyeon felt really weird with Oyabun decision. Eventhough he was her grandfather but seriously, their relationship is basically only based on boss-henchman relationship.

Kai arrive without warning one hour after that. Jiyeon really feel moody.

"You look horrible, Jiyeon-san" 

"Shut-up and go away. Leave me alone" Jiyeon just sit in the sofa, ignoring Kai.

"Really not like you? With that baggy sore eyes, red nose. Are you crying?Hmm.." Kai sighed. She 's just a typical girl, though. 

"I really doesn't have mood today and please go away." Jiyeon pushed Kai towards the door, opened the door and push him outside. Kai was surprised but he still smiling. "Jiyeon, good luck for the trip." Jiyeon just stare at him. How the hell he know about the trip? 

"...basically the mission" Kai said again before iyeon closed the door. Damn Kai! Jiyeon sit in front of the door, leaning on it while her eyes capturing her suitcase for tomorrow trip, the suitcase which contained not only cloth but also a firearm along with a set of bullets in a box. She sighed. It just started...
