[Soft-bellied and dark little author vs. Cool daddy professor] [New Year + Taboo + Full of Tension] Tang Chun didn't understand why a proud girl like her sister Tang Wei, who was holding the moon in front of the stars and controlling the wind and rain, still wanted to get involved with her boyfriend? Although her mother has told her since she was a child that she should submit to others and endure her anger. But Tang Chun felt that it would be more satisfying to fight tooth for tooth. So on a dark and stormy night, she eagerly climbed into the bed of her soon-to-be brother-in-law Lu Changyou... Later, Tang Chun couldn't understand even more. Why was a proud man like Lu Changyou, who was unparalleled in magnificence and dignity, so paranoid in this game of love between you and me?
