The twin sisters of the Ye family have vastly different personalities.
Ye Weiyi is naturally lively and cheerful and doesn't take to her parents' scolding often, having a lot of friends she met outside.
Conversely, Ye Jiajia is gentle, virtuous, understanding, and generous. Whenever she has free time, she goes home to keep her parents company.
The sisters have contrasting personalities, inevitably leading to their disagreements.
Ye Jiajia is also stubborn; after trying to persuade Weiwei many times to no avail, she finally gave up calling Weiwei her elder sister and started to call her by her name directly.
"Mum." Ye Jiajia comforted her, "Weiwei will come around. She'll get married. Don't worry."
"If only your sister were as understanding as you," their mother sighed on the other end of the phone. "Remember what I told you, eat one folic acid tablet every morning."
"I know, mum. I've to go now. I'm at the airport."
