Zhang Xian, who was about to get engaged, found out that her boyfriend of three years had been keeping in touch with her first love behind her back, and left midway on the day her parents met to be with Bai Yueguang. "It's not that I don't love you, because you are not the first person I love, so I can't devote myself wholeheartedly. Have you heard of the law of diminishing love?" Zhang Xian thought that love means never looking back, but when Bai Yueguang showed up at her door with a pregnancy note, she suddenly sobered up. Then when Pei Yuanfei, who had been planning for a long time, approached, Zhang Xian became angry: Doctor Pei, please respect yourself.
