Female protagonist: Song Wanyin (25 years old), who was originally a restorer of modern ancient books. Her soul was transformed into the embarrassing "elderly roommate" of the Hou Mansion. She is gentle and tolerant on the surface, but in fact she is sober and tough, good at observation, fluent in writing, and good at people's hearts.
Male protagonist: Xie Lin (18 years old), the crown prince of Yongning, a noble and aloof new noble in the court, but deeply paranoid and obsessed with "Sister Yin" who taught him how to read ten years ago.
Key contradiction: After ten years of reunion, she is the forgotten old person, and he is the master who controls life and death. He thought she wanted to cling to his dodder flower, but she just wanted to save enough money and leave quietly.
Purpose: The deep courtyard of an ancient house cannot trap the awakening soul.
Even if she is treated lightly at the beginning, she still has to use her wisdom and professionalism to find a way out;
Even though he was once regarded as a clinging dodder flower, he learned respect and perfection through love.
