Lin Jianzhi has been secretly in love with Zhu Liheng, the school sweetheart, for two years, and aims to take the college entrance examination with the goal of going to University A where he is studying. One month before the exam, Zhu Liheng returned to school to give a speech. She was so nervous that she couldn't control her tears, and she looked embarrassed and was knocked upside down. She thought she would be disliked, but instead she waited for Zhu Liheng's daily pick-up and drop-off, math tutoring and school selection analysis. She hid her excitement on Weibo, thinking it was a one-way crush, but she didn't know that Zhu Liheng had recognized her account long ago. As a neighbor, he has been thinking about this little crybaby whose cries can shake the building for two years. His purpose is very simple, to take the little crybaby home and keep the little crybaby as his own.
