It mainly uses various characters living in Chang'an to narrate their trivial matters in Chang'an in the first person. A life-long story from a seven- or eight-year-old baby to a teenage boy who started to have a desire to raise a baby in his twenties and thirties.

The protagonist keeps it a secret, so that there will be surprises~
