Everything is on me

"Kai Xin! Kai Xin!" Kai An whispered at his sister.

When she heard someone calling for her, she blinked and quickly got out of her thoughts.

Looking at Kai An, she asked, "What?"

"Nai Nai is asking you about your boyfriend's occupation."

Turning to Grandma Zhen, Kai Xin respectfully answered, "He's a businessman."

"He sounds old," said Grandma Zhen.

Hearing her grandmother's first opinion of him, Kai Xin chuckled, "Is he? I supposed he does have a deeper set of voice."

"How old is he?" asked Mr. Zhen.

Kai An raised a brow curiously when he heard his father. It was rare for him to take an initiative to ask about Kai Xin's life.        

Without any intention to mince words, Kai Xin answered truthfully, "40. Well, he just had his birthday, so he's 41 now."

"What?!"

Everyone except from Kai An who knew gasped. Mr. Zhen even dropped his chopsticks when he heard.
