#A Grateful Mistake#
Omake================================
December Year 2020
Amusement Park where Katsuo get lost
================================“Katsuo! Don’t play with mama, come out” Atsuko looking around worriedly. She’s been searching Katsuo for 3 hours non-stop. Her eyes are red and her face soaked by tears. She touches her wedding ring, remembering the scene two years ago… when Kai leave…
FlashbackI married him for three years and we have a cute boy named Katsuo. I am very happy but also feel a bit sad with my current state, the fact that we are secretly married… without any announcement to the public, only a simple wedding in the church. Kai have to secretly visit us to avoid reporters. At first, he is objecting about married secretly with me but I insist because I don’t want to ruin his reputation and his carrier since he is very famous now.
“Atsuko, if you want me to stay… I will cancel this contract. I won’t go to Paris” he said.
“I’ll be okay with Katsuo. We will wait you here.” I lied.
The truth is I want you to stay. But I can’t stop you from reaching your dream. I know you actually really want to take this opportunity, this experience to filming in outside country.
“Papa, when meet?” Little Katsuo is in my arms, he reaches his little hands to ask a hug from his father.
Kai hold Katsuo little hands gently, “Let’s meet next year in the amusement park” he then looks at me, “I’ll come back before Christmas, let’s reunite in amusement park, okay?”
I simply smile and nodded.
He told me that he has to go to Paris filming for one year… with the Diva-Ray. I read rumors and gossips about them. They are the top scandal in this year. Many magazines and news are reporting them as a couple. Of course I don’t believe what they written because I have my faith on Kai… I trust him. He said the filming only takes a year but he already gone for two years. Two years without any news from him.
Flashback end// I guess he must be really gets together with that damn Diva right now// Atsuko’s thought.
She is desperately in finding Katsuo and give up. She reluctantly sat under a tree, held her knees and buried her faces between it… crying in silent.
---------------------
At the same time
“Argghhh… why doesn’t she pick up the phone?” Kai face is gloomy like having a black cloud and thunder above his head. He is walking around in amusement park and busy to call Atsuko “She must be mad at me, I promise to come back last year but ended up having little problem and get delayed for another year.” The fact is he just arrived from the airport and immediately runs into amusement park.
At the same place, Mr. Santa arrives in the right place where Kai was.
“Hoooo Lucky! His Papa is here! Hohohoho…”
He drop Katsuo down and whisper something beside his ear, “You remember nothing after bumps into me, you’re running away from your mama to go find papa.” Mr. Santa blows a silver powder on Katsuo.
Katsuo open his eyes and runs apart from Mr. Santa like when he is running away from his mother. He keeps running and then bumps into someone before him. Fortunately, the man holds him so that he didn’t fall to the ground. He lifted up his head to apologize.
“Sorr-” he paused a bit and his face shines of happiness. “PAPA~!”
“Ka…Katsuo?” Kai lifted him up and hug him, “Wow, you’ve grown up. I miss you sooo much”
“I miss you mooooooore much” Katsuo punch Kai’s cheek. “Why makes you so long to see me?”
“Hohohoho… bless you~” Mr. Santa watched from afar then disappeared into the shadow.
“I’m so sorry, Katsuo. Oh yeah, where’s Mama?” asked Kai.
Katsuo looked down, “I’m sorry Papa, I… I run away from Mama just now.”
Kai pinches his son’s nose, “How can you leave your mama alone?”
Katsuo pouts and his eyes are teary, Kai can’t stand to look at his son’s expression, “Don’t looking at me with those eyes. Let’s find your mama together”
--------------------
“Mama!!” Katsuo finally found Atsuko.
Atsuko heard Katsuo’s voice and lift her head to see where the voice came. She saw Katsuo running towards her. She gets up and run over Katsuo in embrace. “Where did you go? Do you know how worried I am?”
“Mama, sorry. Don’t cry, please” Katsuo wipes her tears and place a kiss on her cheek. He then hold Atsuko’s hands and bring her to where Kai is. “Look! I meet Papa!” he said excitedly. He grabs Kai’s hand and guides him to hold Atsuko’s.
“Hi…” only a simple word came out from Kai’s mouth while Atsuko keeps silent.
Cotton candy~ Cotton candy~“Papa, I want that” Katsuo reach out his hand to ask some money from Kai and Kai took out some money for him. After get the money, Katsuo went to buy the cotton candy.
“Acchan, it’s been a long time since we meet each other. Don’t you miss your husband?” Kai approach Atsuko and spread his arms for a hug.
PLLAAAAKKAtsuko gave him a slap. “Don’t touch me. I have no relationship with stranger like you. Please continue enjoying your sweet Diva.”
“Atsuko…?” Kai grab Atsuko arms to prevent her going away.
“I saw it in magazine! Kisses between you and her!” Atsuko raise her voice to Kai.
“That’s just a scenario! I even brushed my mouth several times after kissing her. Really!” Kai explained.
“Just a scenario? She even said that you are hers and she is yours to public!” Atsuko struggling to free her arm from Kai.
“I’m still yours, I won’t belong to anyone else.” Kai tighter his grab.
“You said you only go for one year but you go entirely two years. Just tell me you are enjoying your holiday with her for entire year?”
“That’s not true! I got robbed when I’m buying souvenirs for you. They stabbed me and I have no choice but to nurse in the hospital. They also got my passport. The police spent months to get it back and they won’t let me back until they catch those robbers.” Kai flip his shirt up and exposes his stomach where a scar can be seen.
Atsuko shocked. She freeze on there for a moment, she slowly reaches her hand to touch at Kai’s scar. “I’m sorry to raise my voice at you. I’m sorry…” she moves her hand to touch Kai’s cheek where she slapped. “Is it hurt?”
Kai nodded, “Very hurt…” he leaned his cheek forward to Atsuko “I believe it won’t hurt anymore if you kiss it”
Atsuko doubt in a moment before leaned forward to place a kiss on his cheek. As her lips just a few centimeters away, Kai turn her head and ended up having Atsuko’s lips on his. He smiles and wraps his arms around Atsuko.
Atsuko pushes Kai away immediately, “Kai, not in public. Many people here.”
“So what?” Kai leaned in again and this time, he won’t let Atsuko push him away. Their kisses went into passionate one.
After minutes of kissing, Katsuo sneaked between them after buying the cotton candies. “I want kisses too!”
Both Kai and Atsuko smile shyly and blushing hard to be witness kissing in front of their son. They knelt down beside him and place a kiss on his cheek. Katsuo is smiling happily. Soon, Kai lift up his son with one hand and another hand is holding Atsuko’s. He leads them to the crowd.
“I’m gonna announce here… to tell the public that I have the most beautiful wife and an adorable son”
“Kai, you are crazy” Atsuko freeze on her spot immediately. “I don’t want to break your carrier”
“This is not fair for you two. I don’t wanna visit you secretly anymore”
Kai took a deep breath readily to shout in the crowd. But something big and white hit his head before he can spread a word. Mariko came out from nowhere holding her big paper fan. “You are my money tree. I won’t let you do anything reckless.”
She claps her hands and two men in black suit appeared behind Kai. She took Katsuo away from Kai and gave him to Atsuko. “He is run away from a TV show. I’ll send him to your house after we finish the show.” said Mariko to Atsuko.
Clap clapMariko claps her hands and those two men in black suit dragged Kai into to the mini van. Kai was crying like a kid having his toys snatched by other. “Atsuko~”
“Sorry Atsuko, I promise two more years, I’ll end his contract. After that I will let him officially announces your status to public” Mariko is waving her hands to Atsuko and went into the van.
Atsuko and Katsuo still can hear Kai’s cry in the van.
// It’s so hard… to be married with an idol // Atsuko sighed.
