"Whose wife am I gonna be??" Tang Nan turned his head, looked at his sister, and asked curiously.
"Gu Yu."
"Oh..." Tang Nan lowered his head, took another bite of the chocolate cake in his hand, then suddenly looked up and said to Tang Yuran, "Isn't it said that if you kiss on the lips, you become husband and wife??"
"Who said that??" Tang Yuran looked down at him.
"On TV, ah." Tang Nan answered earnestly.
"Everything on TV is a lie, I've kissed him, but he still doesn't want me to be his wife." Tang Yuran felt somewhat aggrieved.
"Kissed where?"
"Kissed on the lips, ah."
"Then..." Tang Nan thought for a moment, then continued to ask, "Is it because you guys didn't kiss long enough?"
"Huh? What do you mean??" Tang Yuran blinked and looked at her brother.
"People on TV kiss for a long time." Tang Nan mumbled to his sister, "And they bite each other's lips while kissing."
