Chen Sheng returned to the day when his love letter was put on trial, ten days before the college entrance examination. Because of his thick skin, the cold school flower sister turned into a crybaby. The yandere imperial sister, loving, jealous yet magnanimous, became the family's head housekeeper. The gentle knife girl is a Miao girl, gentle and brave; encountering Chen Sheng on the road, she was coaxed into becoming the financial head housekeeper. Later, someone asked Chen Sheng why his backyard is so stable. Chen Sheng smiled and replied, because I have an elder sister managing the backyard.
