A traffic accident left this talented math doctor with only 80 minutes of memory. At that time, all memories will automatically return to zero and start over. When he is speechless, he always uses numbers instead of language to communicate with others in a unique style. He was covered with paper clips to fill his 80-minute memory. This time, the new housekeeper apricot took her 10-year-old son to take care of the doctor's daily life. For apricot, every day is also a new beginning with the doctor. The doctor loves apricot's son very much and calls him "root number", because the root number can accommodate everyone and everything. He uses mathematical formulas to let mother and son know the beautiful and brilliant world. Because there are only 80 minutes, every moment that three people get along with is precious.
