Xu Niannian was designated by her class teacher as Jiang Chenxi's "high school sprint partner", but she didn't know that Jiang Chenxi was the son of the school director. His father gave him a fatal order: he must score 710 points in the college entrance examination in order to inherit the family fund and do scientific research. Jiang Chenxi needed someone who could keep him studying at an efficient pace, so he drew up a "study contract" under the guise of love, but in fact strictly planned his study schedule. Xu Niannian thought this guy was sick at first, but when she discovered that her and Jiang Chenxi's complementary learning methods made their grades improve rapidly, she began to take this "fake love" seriously. What made her heart beat even more uncontrollably was that in the study schedule planned by Jiang Chenxi, there was a line of small words at 5 pm every day: [5:00-5:30 secretly look at Xu Niannian (not a study item, but a necessary daily adjustment)].
