Zhao Xin was truly meticulous and knew exactly the ripe time to reveal Zhao Kai's presence to him.
With many guests sending many precious gifts to him, his mood peaked high.
He was clearly blissful, so when Zhao Xin brought up this uncomfortable topic, what more could Zhao Gaofu do in response?
Reprimand her?
That he could not bear to do, considering she had been managing the company and the party well.
Reject her?
That was also impossible, given the guests lining up to give him a birthday present could hear Zhao Xin's words.
She did not lower her tone but spoke in a normal tone. The further people in the line might not be able to hear it well, but it was definitely not true for those in front of the lines.
Unless they were deaf, it was impossible for them to not hear it.
Thus, Zhao Gaofu called Zhao Xin a naughty girl because she cornered him on his birthday.
