Naru looked at his mirror image for answer.
"Yes brother! At last, there's someone who will take us both, aren't you happy? And Mai!" Kazuma chirped.
Yes he is happy, but the thought of Mai will also be adopted with them didn't make him happy at all, for she will become his sister if that will happen.
"You… don't like to come with us?" Luella saddened at the thought seeing the young boy's conflicted expression.
"I liked to, but…" He looked at Mai, who give him a force encouraging smile. Miss Sunshine entered the room to serve them tea. "But we promised to get married when we grow up."
Luella spluttered her tea; Martin almost choke his; Sister Hilda gasp; and Kazuma giggled.
"If you will also adopt her, she will become my sister. And I don't want that!" He stated firmly.
"What?!" The adults asked the kid.
"We can't become a sibling!" Naru repeated. "We promise that we will study hard, get a good job, then someday we will get married." Naru make it clear to them.
Mai was blushing hard.
"Oh Martin, they are so lovely. A childhood promise, how sweet." Despite on being in her early thirties, Luella can't help but blush. Martin was smirking at Naru, which made the boy slightly blush.
"Alright, we will not adopt Mai, but only the two of you." Martin said "Will that be okay?" He asked the conflicting boy.
Naru don't want to leave her alone, but he don't want her to become his sister either.
"So what's your decision, Kazuya?" Sister Hilda asked the boy.
He looked at Mai's teary eyes "Will you be okay here?" He asked and she softly nodded. He then looked at the couple "Kazuma and I will come with you, Professor Davis, Mrs. Davis"
"You can call us mom and dad." Luella stated, beaming at him.
"Yes!" Choki held his fist up high.
"Pack up your things, while we will process the papers, okay?" Sister Hilda patted Naru's head. She guided the couple to her office for the legalization.
Mai was sobbing as she watched Naru and Choki started packing. When he closed the zipper of his bag, Choki went to her and hug her tightly.
"Be a good girl here Mai, okay? We will meet again. I promise you that." He's also crying now "You will always be my little sister." It only made her cried harder.
"C-Choki…" she sobbed "Take care of yourself, take care of Naru, alright?"
He nodded. He pulled away from the hug to look at her, he wipe her tears away. "You're a mess." he teased, he chuckled when he saw her pouted.
He left first to give her and his brother a time to say goodbye.
When he heard the door close, Naru immediately rush and give her a bone crushing hug.
"You know, you looked and sounded like you're mourning for us right now." He teased, hoping to calm her down. He held her face with his hands and look in her deep brown eyes "We will meet again, and when we grow up, we will get married, Mai. I promise." He vowed and handed him a silver key.
"That's the key to my former room from our former house. I want you keep it. And if I become a successful man someday, I will replace it with beautiful engagement and wedding rings."
Fresh tears rolled on her cheeks, she fingered the gold necklace on his neck. "Take care, okay? Don't give your parents a hard time."
He nodded while crying.
A knock disrupt them, and Luella open the door and smile warmly at the sight. They were hugging each other.
"I will miss you, Naru."
"I will miss you too, Mai." She was blushing furiously, and he knew it.
He chuckled and reluctantly pulled away from the hug. Mai joined them in going downstairs. They were saying goodbyes, Mai hugged the two before they went inside the car.
When Miss Dawn and Miss Sunshine closed the gate, Sister Hilda hugged to comfort the sobbing brown-haired girl.
