In Futaba Kindergarten, the Kasukabe Defense Team composed of Kazama, Xiaoxin, Nini, Zhengnan and Dumb began a journey of growth full of laughter and touching. Inside and outside the classroom, they responded to challenges with unbridled creativity - Fengjian stayed up all night to compete in the math competition, and Xiaoxin used the "Butt Song" to relieve tension; during the English speech, Nini designed the look and Zhengnan made the PPT, and everyone worked together to help Fengjian win the championship. From environmental protection actions to cultural exchanges, from handicraft competitions to charity sales, every activity has become a touchstone of their friendship, a wonderful blend of rigor and absurdity, seriousness and fun.
