"Xiao Zi," Zhao Huan called out. "What's your opinion regarding their argument? Do you want your son to marry Xixi's daughter or just be a best friend?"
He shrugged his shoulders in reply, "I'll be happy as long as they are happy."
"Ah-Xin, are you going against me?" questioned Wen Ai.
"No, he is giving his unbiased opinion," answered Su Xixi for him.
"By the way, Xixi, what are doing here? Did you come for a surprise visit?"
Su Xixi facepalmed herself, "I almost forgot because of your wife's nonsense. I'm here to give you both an invitation."
"Invitation?" Xin Zimen opened his eyes and sat straight to look at her. "For what?"
"For my best friend's surprise birthday party," she replied.
Wen Ai furrowed her brows, "I'm your best friend though."
Su Xixi grinned, "Exactly!"
