With the addition of Zhou Ziang, the three of them gathered together and were involved in a series of incidents such as class competitions, clubs, and family turmoil. Each volume depicts the team's running-in and growth, including youthful troubles, emotional ups and downs, and hilarious oolongs and coincidences.
